A student obtains a sharp image of the distant window (W) of the school laboratory on the screen (S) using the given concave mirror (M) to determine its focal length. Which of the following distances should he measure to get the focal length of the mirror?

The shiny outer surface of a hollow sphere of aluminium of radius 50 cm is to be used as a mirror:
Which type of spherical mirror will it provide?
An optical device has been given to a student and he determines its focal length by focusing the image of the sun on a screen placed 24 cm from the device on the same side as the sun. Select the correct statement about the device.
(A) Convex mirror of focal length 12 cm
(B) Convex lens of focal length 24 cm
(C) Concave mirror of focal length 24 cm
(D) Convex lens of focal length 12 cm
In each case (a) and (b), draw reflected rays for the given incident rays and mark focus by the symbol F.

Complete the following diagrams shown in Fig. by drawing the reflected ray for each of the incident ray A and B.

The diagram below in Figure, shows a convex mirror. C is its centre of curvature and F is its focus. (i) Draw two rays from A and hence locate the position of image of object OA. Label the image IB. (ii) State three characteristics of the image.
Name the kind of mirror used to obtain:
A real and diminished image.
The magnification for a mirror is -3. How are u and v related?
What is the relationship between the focal length and radius of curvature?
Complete the following diagrams shown in the below figure by drawing the reflected ray for each incident ray.
