NCERT Exemplar for Class 10 Science Chapter 10 Light-Reflection and Refraction Soln: Answer is (a) Concave lens Explanation: Answer is concave lens because incident rays are parallel and emergent rays are diverging. Concave and convex lenses are the two most common types of lenses, and they cause light rays to diverge and converge, respectively. Concave Lens: Concave lens has a surface that bulges inward towards the centre, and thus it diverges the light beam. For a concave mirror to focus light coming from a distance to a single point, in a similar fashion to a concave lens, it must have a parabolic shape. Draw a ray diagram and use the information from the ray diagram to fill in the box. Ray diagrams are constructed by taking the path of two distinct rays from a single point on the object: A ray passing through the center of the lens will be undeflected. Explain the Ray Diagrams for Mirrors? To figure out the position and size of an image reflected by a curved mirror, you can draw a scaled diagram of the mirror as follows: along the principle axis are the center of the radius of curvature of the mirror, C, and the focal point of the mirror, F, which is half-way between C and the mirror. The position of the image formed by the lens ii. An incident ray which is directed towards the object focus of the lens is refracted parallel to the optic axis. 0 cm object is placed 10.

To draw the ray diagrams by keeping an object at different distances from the convex lens and finding out nature of the images formed. Solve: The figure shows the ray-tracing diagram using the steps of Tactics Box 23. With a concave lens, the image will always be diminished, the right way up and virtual. Ray diagram helps us to study the nature, position and relative size of the image formed by lenses. Converging Lens. Images come in two categories :. Cat 5 Wiring Diagram. When a ray, parallel to principal axis strikes concave or convex lenses, the reflected ray passes through a focus on the principle axis. The diagrams below depict the refraction of light through various lenses. On a separate sheet of paper, answer the following questions. For Case 4, merely construct the ray diagram. Consider a concave lens made out of air that is im-mersed in water (perhaps two watch glasses glued to each end of a piece of pipe, with air inside). c) real, upright, and smaller.

Chapter 10 Class 10 - Light - Reflection and Refraction. Title: CONVEX LENS 1 WELCOME. Description Simulation of image formation in concave and convex mirrors. We have already studied that the geometric centre of a spherical mirror is called its pole while. Location is same side as object or opposite side, Orientation is upright or inverted, Size is smaller or bigger, Image type is real or inverted. Students will then be formally taught lens diagram terminology as well as the ray diagram laws of refraction. Using this diagram and simple trigonometry, demonstrate that the ratio of image height to object height equals the ratio of image distance to object distance and under what conditions this is true. From the ray diagram, characterize the image. By manipulating the object and mirror locations, you can create real or virtual images.

Ray Tracing: Ray tracing can be used to better understand the size, location and nature of the image formed by a converging lens. Concave Mirrors. Lens Formula. Convex Lens Concave Lens Ray Diagrams Lenses To draw ray diagrams for lenses use two of the following rays: 1. (11) Draw a ray diagram for a diverging lens that has a focal length of -10. The diagram shows a ray of light hitting the surface of a mirror made from thick glass. In this case, the lens has been shaped so that all light rays. Likewise, a concave or diverging lens is shaped so that all rays that enter it parallel to its optical axis diverge, as shown in part (b). An object 1 cm tall stands 6 cm in front of a lens with a focal length of +2 cm. 67 cm from the lens on the other side. The main difference between concave and convex lens is that a concave lens is thinner at the centre than it is at the edges, whereas a convex lens is thicker at the centre than it is at the edges. Author: Lenore Horner. There are two types of lenses, the concave and the convex lens. Observe how the light ray is affected. Find the size of the image. For example, a 10 cm focal length convex lens has a power of +10 m-1; while a 20 cm focal length concave lens has a power of -5 m-1. A convex lens focuses light rays, and therefore is also known as a converging lens. From the tip of the object horizontally toward the lens, refracting through the focal point. The distances on the diagrams are not to scale. A diverging lens ray diagram follows three basic rules: Any ray of light that is parallel to the. Although may also be useful for other boards/A-Level Answer sheet available! Both word and pdf worksheets available. The mirror and the lens are likely to be (a) both concave. So, as per the new scale, Focal length, f = -3 cm Image distance, v = -2 cm Steps to draw the ray diagram is mentioned below as follows: (i) Draw a horizontal line which is called the principal axis. A lens with one convex and one concave side is convex-concave or meniscus. This first step is the same regardless of the type of lens. This session will mainly be around the "Ray Diagrams of Mirrors and Lenses" Concave and Convex Mirror and Lenses with proper Explanation. (c) Pita looks at a vase through a concave lens. However, with a concave lens, we always get virtual, upright, and diminished images. 4 cm from the lens's surface. When drawing ray diagrams Pb jec t Grade 8 Science Ray Diagrams for Concave Mirrors 1 The incident ray: this is the incoming ray that will hit the solid surface/barrier (eg a mirror) 2 The reflected ray: the ray that bounces off the barrier 3 The normal: this. Each surface can be convex (bulging outwards from the lens), concave (depressed into the lens), or planar (flat). About channel:-Ur Shiksha We make it simple For Class:- 9th, 10th, 11th, 12th. Answer: Image Formation by Lens For making the image by thin lens, the ray diagram is traced according to following three rules. Ray diagrams for such lenses are drawn using: a ray from the top of the object through the middle of the lens; a ray from the top of the object parallel to the principal axis.
