In Figure, `m\ and\ n` are two plane mirrors perpendicular to each other. Show that the incident ray `C A` is parallel to the reflected ray `B D`

In Figure, P Q\ a n d\ R S are two mirrors placed parallel to each other. An incident ray A B strikes the mirror P Q at B , the reflected ray moves along the path B C and strikes the mirror R S and C and again reflects back along C D . Prove that A B||C D .

In Fig. 6.33, PQ and RS are two mirrors placed parallel to each other. An incident ray AB strikes the mirror PQ at B, the reflected ray moves along the path BC and strikes the mirror RS at C and again reflects back along CD. Prove that AB || CD.

Two plane mirrors are inclined to each other such that a ray of light incident on the first mirror and parallel to the second is reflected from the second mirror parallel to the first mirror. Determine the angle between the two mirrors:

The diagram below shows a light ray striking and reflecting from a plane mirror AO is the incident ray and OB the reflected ray. The angle between the incident ray and the reflected ray is 120^@ . If two plane mirrors are used and kept facing parallel to each other, how many images are formed if the object is kept in between them?

The diagram below shows a light ray striking and reflecting from a plane mirror AO is the incident ray and OB the reflected ray. The angle between the incident ray and the reflected ray is 120^@ . What is the value of the angle of reflection?

A ray is reflected in turn by three plain mirrors mutually at right angles to each other. The angle between the incident and the reflected rays is

For a fixed incident light ray, if the mirror be rotated through and angle theta (about an axis which lies in the plane of mirror and perpendicular to the plane of incidence), show that the reflected ray turns through an angle 2 theta in same sense.

The diagram below shows a light ray striking and reflecting from a plane mirror AO is the incident ray and OB the reflected ray. The angle between the incident ray and the reflected ray is 120^@ . If the image of an object is formed 5 cm behind the mirror, what is the distance between the image and the object?

Find the angle between two plane mirrors such that a ray of light incident on the first mirror and parallel to the second mirror is reflected from the second mirror, parallel to the first mirror.

A light ray is travelling from air to glass. True reflected and refracted rays are perpendicular to each other. If the angle of incidence in air is I the refractive index of glass is
