State the direction of incident ray which after reflection from a spherical mirror gets reflected along its own path. Give a reason.

What do you understand by the focus and focal length of a spherical mirror? Show them on separate diagrams for each of a concave mirror and a convex mirror.

How is a spherical mirror used to diverge a beam of light from a point? Name the type of mirror used.

Draw suitable diagrams to illustrate how a beam of light incident parallel to the principal axis is reflected by:

(a) a concave mirror and

(b) a convex mirror.
