What is the angle of reflection, when a ray of light is incident normally on any mirror (spherical or plane)?

Write the value of angle of reflection for a ray of light falling normally on a mirror.

Which one of the following is the correct angle between the incident and reflected rays when a ray of light incident normally on a plane mirror?

P is small angled prism of angle 3^(@) made of a material of refractive index 1.5 . A ray of light is incident normally to the mirror as shown in figure. M is a plane mirror. The angle of deviation for the ray reflected from the mirror M with respect to the incident ray is :

A mirror and source of light are situated at the origin O and a point on OX respectively. A ray of light from the source strikes the mirror and is reflected. If the DRs of the normal to the plane of mirror are 1,-1,1, then DCs for the reflacted ray are :

A ray of light is incident on a plane mirror, making an angle 'q' with the surface of the mirror. Arrange the following steps in sequential order to calculate the angle between the incident light ray and the reflected light ray. (A) Draw a normal line on the plane mirror at the point of incidence of the light ray. (B) Note down the angle between the plane mirror and the incident light ray. (C) The sum of the angle of incidence and the angle between the plane mirror and the incident ray is 90^(@) .Determine the angle of incidence. (D) From the laws of reflection, the angle of incidence is equal to the angle of reflection. Then the sum of the angle of incidence and the angle of reflection gives the angle between the incident light ray and the reflected light ray.
