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

An incident ray strikes a plane mirror at an angle of 15^@ with the mirror. The angle between the incident ray and reflected ray is

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?

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?

Incidant angle of a ray of light is 30^@ . The angle between the incident ray and the reflected ray is ______.

A ray is incident at an angle 40^@ with a mirror. The angle between the normal and reflected ray is

A ray of light falls on a plane mirror. When the mirror is turned, about an axis at right angles to the plane of mirror by 20^(@) the angle between the incident ray and new reflected ray is 45^(@) . The angle between the incident ray and original reflected ray was therefore.
