Two plane mirrors makes an angle of `120^(@)` with each other. The distance between the two images of a point source formed in them is 20 cm . Determine the distance from the light source of the point where the mirrors touch, the light source lies on the bisector of the angle formed by the mirrors.

Two plane mirrors are inclined at an angle of 60^(@) . An object is placed between the mirrors. The number of images formed by the two mirrors is

A convex mirror of radius of curvature 70 cm and a plane mirror are placed face. The distance of separation between the mirrors is 28 cm. If a point source is placed on the principal axis in between the mirrors, two images are formed in the plane mirror. Determine the distance of the two images from the plane mirror.

Two plane mirrors are placed parallel to each other. The distance between the mirrors is 10cm. An object is placed between the mirrors at a distance of 4cm from one of them, say M_(1) . What is the distance between the first time formed at M_(1) and the second image formed at M_(2) ?

When a point source of light is kept near a plane mirror

The focal length of a convex mirror is 40 cm. A point source of light is kept at distance 40 cm from the mirror. Find the distance of image from the mirror.
