• The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. In this section, let us look at the types of images formed by a convex mirror. When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is much smaller than compared to that of the object
• The size of the image is much smaller than that of the object. When an object is placed at a finite distance from the lens, a virtual image is formed between the pole and the focus of the convex lens. The size of the image is larger than that of the object. Summary of Image Formation by Concave and Convex Lens
• The location, orientation, size, and type of image formed by a convex lens are related to the position of the image location in front of the lens. Object >2·F = The image formed by a convex lens when the object is located more than twice the focal length from the lens

### Concave Mirrors And Convex Mirrors - Image Formation, Ray

ray diagrams were constructed in order to determine the location, size, orientation, and type of image formed by double concave lenses (i.e., diverging lenses). The ray diagram constructed earlier for a diverging lens revealed that the image of the object was virtual, upright, reduced in size and located on the same side of the lens as the object The magnifying glass is a convex (or converging) lens, focusing the nearly parallel rays of sunlight. Thus the focal length of the lens is the distance from the lens to the spot, and its power is the inverse of this distance (in m)

Note that for the convex mirror the reflected rays DIVERGE (this is also the case for the concave mirror when the object is closer than the focal point to the mirror). In these cases the image formed is virtual - light rays do not pass though it, but to an observer appear to come from it.; Perhaps the most common everyday experience of a convex mirror is the passenger side rear-view mirror. The image of a candle is formed by a convex lens on a screen. The lower half of the lens is painted black to make it completely opaque. Draw the ray diagram to show the image formation. How will this image be different from the one obtained when the lens is not painted black Draw a ray diagram represent the nature , position and relative size of the image formed by a convex lens for the object placed : (a) at 2 F 1 (b) between F 1 and the optical centre O of the lens. Which of the above two cases shows the use of convex lens as a magnifying glass ? Give reasons for your choice

### Image Formation by Lenses Physic

When we describe the image formed, we can use the acronym LOST (Location, Orientation, Size, Type). This image is L - between F and C, O - inverted (upside down from original), S - smaller than original and T - a real image (on the same side of the mirror). • C 10 Figure $$\PageIndex{12}$$: A light bulb placed 0.75 m from a lens having a 0.50-m focal length produces a real image on a screen, as discussed in the example. Ray tracing predicts the image location and size. Strategy. The image must be real, so you choose to use a converging lens (A summary of the three cases or types of image formation appears at the end of this section.) A different type of image is formed when an object, such as a person's face, is held close to a convex lens. The image is upright and larger than the object, as seen in Figure 10b, and so the lens is called a magnifier A convex mirror is a diverging mirror (f is negative) and forms only one type of image. It is a case 3 image—one that is upright and smaller than the object, just as for diverging lenses. Figure 7a uses ray tracing to illustrate the location and size of the case 3 image for mirrors A ray diagram is a tool used to determine the location size orientation and type of image formed by a lens. In this lesson we will see a similar method for constructing ray diagrams for double concave lenses. And a virtual image is formed when an object is located less than one focal length from a converging lens ie in front of f

Understand that we need rays (at least 2) for image formation of a point object. Explain the three types of rays to locate an image. Analyze nature of images (size, orientation, real / virtual) through a Convex and concave lens for different object distance through an experiment

The purpose of the following investigation is to demonstrate various characteristics of the types of images formed by convex and concave lens. The object (the arrow on the right) will be placed at various distances from the lens as a thought exercise and we will use the rules of image formation to find where the image would form and how to. For each location, practice the L.O.S.T art of image description - that is, describe the image Location, Orientation, Size, and Type. Record your observations using Table 1 on the reverse side by circling the appropriate descriptor. 2. Convex Mirrors: Use same values of focal length and object height 2. F. and. F. F. This means that the object is between two principal focal lengths and one principal focal length from the convex lens. As in the previous section, we use the two ray diagram rules. From the above diagrams we can observe that all the images are located beyond two principal focal points ( 2F 2 F) on the other side of the convex lens same size. 1.

4. Types Images Images can be one of two types. First it can be real or virtual. An example of this is an object placed far from a convex lens. Magnified Image: If the image is larger than the original object it is called magnified. An example of this is an object that is placed very close to a convex lens. All real images formed by lenses.
5. In convex lens, the focal length is positive. Real Image and Virtual Image for Convex Lens. Real Image: A convex lens can be used to produce a real image, and this occurs if the object is located at a position of more than one focal length from the lens. It is projected in front of the lens and can be captured on a screen

The concave lens is known as the diverging lens because it diverges the rays after they pass through it, The image formed by the concave lens is a virtual image because it can not be received on a screen. Uses of the concave mirror and the convex mirror in our daily life. The properties of the image formed by a plane mirror No, convex lens can form both real and virtual images depending upon the position of object placed in front of lens. Convex lens can form a virtual image only when the object is placed in between the focus and optical centre of lens. A point object is placed 60 cm in front of a convex lens of focal length 30 cm A converging lens is also known as a convex lens. , 2. The distance between both focal points is called the focal length. , 3. All rays that are parallel to the optical axis in a converging lens converge towards the focal point. , 4. A converging lens forms a virtual image when the object is within the focus length Ray diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a concave mirror. The use of these diagrams was demonstrated earlier in Lesson 3.Ray diagrams provide useful information about object-image relationships, yet fail to provide the information in a quantitative form

There are, again, two alternative methods of locating the image formed by a convex mirror. The first is graphical, and the second analytical. According to the graphical method, the image produced by a convex mirror can always be located by drawing a ray diagram according to four simple rules: . An incident ray which is parallel to the principal axis is reflected as if it came from the virtual.

The Lens Equation An image formed by a convex lens is described by the lens equation 1 u + 1 v = 1 f where uis the distance of the object from the lens; vis the distance of the image from the lens and fis the focal length, i.e., the distance of the focus from the lens. F u f v object image N.B. other sign conventions are sometimes used in. Concave lens always produce upright and virtual images. Convex lens produce either upright or inverted images depending upon the position of the object, which can be either virtual or real. Chapter 26 Geometrical Optics Q.76P A convex lens is held over a piece of paper outdoors on a sunny day An object of size 2 cm is placed 8 cm to the left of a converging lens with the focal length of 6cm.

### Video: Table 2. Location, Orientation, Size, and Type of Image ..

A different type of image is formed when an object, such as a person's face, is held close to a convex lens. The image is upright and larger than the object, as seen in Figure(b), and so the lens is called a magnifier. If you slowly pull the magnifier away from the face, you will see that the magnification steadily increases until the image. An object of height 2 $\mathrm{cm}$ is placed at $50 \mathrm{cm}$ in front of a diverging lens of focal length $40 \mathrm{cm} .$ Behind the lens, there is a convex mirror of focal length $15 \mathrm{cm}$ placed 30 cm from the converging lens. Find the location, orientation, and size of the final image When a negative lens is placed between an object and the eye, it does not form a real image, but reduces (or demagnifies) the apparent size of the object by forming a virtual image. The distinction between a real and a virtual image is an important concept when imaging specimens through a lens or mirror system, regardless of whether the system. Type of image: ­ REAL / VIRTUAL ­ Relative size of the image: ­ BIGGER / SMALLER ­ Image location: ­ IN FRONT OF MIRROR / BEHIND MIRROR ­ Provide a general description of the image of an object placed beyond the focal point of a concave mirror by circling the correct choices below: Image orientation: ­ UPRIGHT / INVERTED ­ Type of image.

Image Formation with Diverging Lenses - Java Tutorial. Negative lenses diverge parallel incident light rays and form a virtual image by extending traces of the light rays passing through the lens to a focal point behind the lens. In general, these lenses have at least one concave surface and are thinner in the center than at the edges 2) The lens is used as a lens system in cameras as they focus light rays for a clear image. 3) Lens has medical purposes as well, like the correction of hyperopia. 4) It is used in a projector. 5) Plano-convex lens is used in a telescope. 6) It is a primary concentrator for multi-junction star cells The focal length of a convex lens is positive, while that of a concave lens is negative. Generally, a convex lens forms a real image, but it can also create a virtual image when the object is in the middle of the focus and optical centre. On the contrary, the image formed by the concave lens is erect, virtual and smaller, than the object How inverted image is formed? The image focussed on the retina with the aid of an optical system is said to be inverted, in contrast to erect, when the orientation of the image is upside-down in comparison to the object as seen with the unaided eye. The image formed on the film or frosted glass plate of a single-lens camera is inverted Figure 16.32 The cornea and lens of an eye act together to form a real image on the light-sensing retina, which has its densest concentration of receptors in the fovea, and a blind spot over the optic nerve. The power of the lens of an eye is adjustable to provide an image on the retina for varying object distances If her face is 20.0 cm from the ball, describe the location, size, orientation and nature of her image. The ball is a convex mirror because the center is located inside the ball. Therefore, f is negative. F is half the radius (which is half the diameter). do= 20.0 cm f = -15.0 cm di= ? m=

### Double Concave Lens Ray Diagra

images are always inverted with respect to the orientation of the object. Virtual images are always upright (i.e. in the same direction) compared to the orientation of the object. For real images the images distance, i is positive whereas for virtual images the image distance is negative. Figure 4: Image formation in a thin lens. v:F0 An object 5 cm in length is held 25 cm away from a converging lens of focal length 10 cm. Draw the ray diagram and find the position, size and the nature of the image formed. Converging lens means a convex lens A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. Such mirrors always form a virtual image, since the focal point (F) and the centre of curvature (2F) are both imaginary points inside the mirror, that cannot be reached The focal length of the lens determines the type of image formed. The convex lens produces a real image when an object is located at a distance (more than twice the focal length). When an object is located within the focal length of a convex lens; the lens acts as a magnifier, forming an upright, enlarged and virtual image

### Image Characteristics for a Convex Lens - Boston Universit

A new type of image called virtual image is formed. It is an illusion formed by the way the light refracts through the lens. Image looks 3D and real but there is nothing where the image appears to be. DEPARTMENT OF EDUCATION / UP NISMED. Convex Lens: Location, Orientation, Size and Type A lens, like a mirror, will form either a real image that can be projected onto a screen or card or a virtual one that cannot be projected. Also, as with a mirror, an image from a lens can appear either upside down or right side up. A convex lens inverts the image; a concave lens does not. Most astronomical telescopes use convex lenses Convex Mirror (this side) Figure 1: Two types of spherical mirrors. to determine the location, orientation, and size of an image. 3. Experimental method: One uses mirrors, a source, and an image screenon an optics =⇒ the image is formed (i.e., comes to a focus) halfway out to the center of curvature
