Mukesh Kumar Gandhi Solutions for Chapter: Light, Exercise 3: Self Evaluation Test

A ray of light strikes a plane mirror at an angle of $32°$ as shown in the figure. What is the angle between the incident and the reflected rays?

Sunlight is incident on a concave mirror parallel to its principal axis. The image is formed at a distance of $26 \mathrm{cm}$ from the pole. Find the radius of curvature of the concave mirror in SI units.

In the given figure, AB is an object, A'B' is its image and MN is the position of the mirror. State the kind of mirror. Also, complete the ray diagram to show the formation of the image.

In a dark room, a parallel beam of light is incident on a plane mirror and another parallel beam of light is incident on a white wall. What will be your observation and why?

Two plane mirrors $M_1$ and $M_2$ are erected $20 \mathrm{cm}$ apart parallel to each other. A point object is placed between them and $5 \mathrm{cm}$ from mirror $M_1$ determine the distance of the three nearest images from the mirror $M_1$.

 What do you mean by lateral inversion? Write the letters of English alphabet which in front of plane mirror do not show lateral inversion.

Find the position, size and nature of the image formed by a spherical mirror from the given data: Focal length, $\mathrm{f}=-12 \mathrm{cm}$, object distance, $\mathrm{u}=-36 \mathrm{cm}$ and size of the object, $O=2 cm$.

An object of size$1.2 \mathrm{cm}$ is placed at a distance of $12 \mathrm{cm}$  from a convex mirror of radius of curvature $12 \mathrm{cm}$ . Find the position of the image and size of the image.
