The angle between the incident ray and emergent ray, when the ray is passing through an equilateral prism is called angle of _____.

The angle between the incident ray and the emergent ray in case of a prism is called angle of prism. _________

The angle between the incident ray and the refracted ray of a prism is called angle of deviation.

Write a relation for the angle of deviation (delta) for a ray of light passing through an equilateral prism in terms of the angle of incidence (i_(1)) , angle of emergence (i_(2)) ang angle of prism (A).

The perpendicular distance between the incident ray and the emergent ray in a glass slab is called the ..................... (angle of emergence/lateral displacement).

The angle between the incident ray and the ray reflected from the plane mirror is 70^@ . The angle of incidence will be:

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.

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.

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?

Write a relation between the angle of incidence (i), angle of emergence (e), angle of prism (A) and angle of deviation (d) for a ray of light passing through an equilateral prism.
