What are the marginal rays?

A concave mirror cannot form :

Discuss the focal plane of spherical mirror

Mention one each use involving the focal plain of concave and convex mirrors.

Where will you keep an object in front of a concave mirror to get a real and diminished image?

An object is placed in front of a concave mirror. It is observed that a virtual image is formed. Draw the ray diagram to show the image formation and hence derive the mirror equation $\frac{1}{f}=\frac{1}{u}+\frac{1}{v}$.
 

Write any one use for the convex mirrors.

Write any one use for the concave mirrors.
