Define the following term in the context of spherical mirrors:- Centre of curvature
Name the two types of spherical mirrors. What type of mirror is represented by the:
back side of a shining steel spoon?
State the two convenient rays that are chosen to construct the image by a spherical mirror for a given object? Explain your answer with the help of suitable ray diagrams.
What is meant by magnification? Write its expression. What is its sign for the (a) real (b) virtual, image?
Select the correct option:
A mirror forms a virtual image (diminished) of an object, whatever be the position of object:
AB is the object, A1B1 is its image. MM' is the position of the mirror. Complete the ray diagram and find the position of the center of curvature and focus of the mirror. Also, measure the focal length.

For measuring the angle of incidence, he must position the protractor in the manner shown in the figure:
A converging lens of focal length f is placed at a distance 0.3 m from an object to produce an image on a screen 0.9 m from the lens. With the object and the screen in the same positions, an image of the object could also be produced on the screen by placing a converging lens of focal length.
