Name the following
The angle between the incident ray and the normal

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 angle of incidence on a plane mirror is 30^@ . The angle between the incident ray and the reflected ray is

In the figure given the angle between incident ray and the reflected ray is 70^@ Find the angle between the mirror and the incident ray.

In the figure given the angle between incident ray and the reflected ray is 70^@ Find the angle of incidence.

Light is incident on a glass surface at polarising angle of 57.5^(@) Then the angle between the incident ray and the refracted ray is

In the figure given the angle between incident ray and the reflected ray is 70^@ Find the angle of reflection.

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.

The refracting angle of a glass prism is 30^@. A ray is incident onto one of the faces perpendicular to it. Find the angle delta between the incident ray and the ray that leaves the prism. The refractive index of glass is mu=1.5.

The refracting angle of a glass prism is 30^@. A ray is incident onto one of the faces perpendicular to it. Find the angle delta between the incident ray and the ray that leaves the prism. The refractive index of glass is mu=1.5.

If the angle of reflection is 45^@ , what is the angle between the incident ray and the reflected ray?
