Figures shows a plane mirror on which a light ray is incident, if the incident light ray is turned by `10^(@)` and the mirror by `20^(@)` as shown , find the angle turned by the reflected ray.

Figure shows a plane mirror onto which a light rays is incident. If the incident light ray is rotated by 10^(@) and the mirror by 20^(@) , as show in figure below, find the angle by which the reflected ray is rotated.

Figure shows a mirror M on which a light ray incident at an angle 40^(@) from normal. If the ray is rotated by 10^(@) clockwise find the change in angle of deviation of light after reflection.

If a light ray incident on a plane mirror makes an angle 30^(@) with it, find the angle of incidence and angle of reflection.

If a ray of light incident on a plane mirror is such that it makes an angle of 30^@ with the mirror, then the angle made by the reflected ray with the mirror 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

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