Question

:) :) :) :) Define the following when refraction takes place an equilateral glass prism
1. angle of incidence
2. prism
3.refracting angle of a prism
4.angle of emergence
5.angle of deviation

Answer 1

Explanation:

ray of light passes through an equilateral glass prism such that the angle of incidence is equal to the angle of emergence and each of these angles is equal to 3/4 of angle of prism. ... Angle of deviation for a ray of light in a prism is given by, Prism is an equilateral triangle.

Answer 2

Angle of incidence

The angle which an incident ray makes with the normal, at the point of incidence, is known as angle of incidence.

Prism

A prism is a piece of glass or any other transparent material which is bounded by two triangular surfaces and three rectangular surfaces. Two opposite surfaces of prism are identical and parallel triangles. But the other three surfaces are rectangular and inclined on each other .

Refracting Angle of Prism

The angle between two refracting faces is called refracting Angle of prism.

Angle of Emergence

The angle of the light coming out of a medium is known as Angle of emergence.

Angle of Deviation

The angle between the incident ray and emergent ray is called angle of deviation.
