Reflection of Light

The image formed by a concave mirror is

To see his complete image, a man of height $h$ requires a mirror of length at least equal to

A plane mirror produces a magnification of

A point object is placed at a distance of $30 \mathrm{cm}$ from a convex mirror of focal length $30 \mathrm{cm}$. The image will form at

Focal length of a concave mirror is $6 \mathrm{cm}.$ If the object is at distance $4 \mathrm{cm}$ from the focus, then the position of the image w.r.t. the focus is

An object is placed at a distance of $40 \mathrm{cm}$ from a convex mirror of radius of curvature $20 \mathrm{cm}$. At what distance from the object a plane mirror be placed so that image in the convex mirror and plane mirror coincides?

A ray of light is incident on a plane mirror at an angle of $30°$. At what angle with the horizontal must a plane mirror be placed so that the reflected ray becomes vertically upwards?
