A ray of light is incident at an angle of 35^@ on a plane mirror. What is the angle between the incident and the reflected rays ?

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

If two plane mirrors are inclined at angle 0 to each other as shown, than angle of deviation of incident ray is

A light ray is incident on a plane mirror making an angle of 45^(@) with respect to the surface of the mirror. The value of the angle between incident ray 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.
