What is the advantage of using a convex mirror as a rear-view mirror in vehicles as compared to a plane mirror? Illustrate your answer with the help of labelled diagrams.

Where would the image be formed by a convex mirror if the object is placed:

(a) between infinity and pole of the mirror?

(b) at infinity ?

Draw labelled ray-diagrams to show the formation of image in both the cases.

The shiny outer surface of a hollow sphere of aluminium of radius 60cm is to be used as a mirror :

(a) What will be the focal length of this mirror?

(b) Which type of spherical mirror will it provide ?

(c) State whether this spherical mirror will diverge or converge light rays.

Give two uses of a convex mirror. Explain why you would choose convex mirror for these uses.

What would your image look like if you stood close to a large :

(a) convex mirror?

(b) concave mirror ?

Give reasons for your answer.
