Question

The angle between the incident ray and the normal is called __________
(A) Angle of incidence
(B) Angle of reflection
(C) Angle of refraction
(D) None of these

Answer 1

Hint : Here we will refer all the given terms and then will find the term to complete the given word statements accordingly. The different angles of measures are found when the light is incident.

Complete Step By Step Answer:
The normal line divides the angle between the incident and the reflected ray into the two equal angles.
The angle between the incident ray and the normal line is known as the angle of the incidence whereas, the angle between the reflected ray and the normal line is known as the angle of reflection.
From the given multiple choices, the option A is the correct answer.

Note :
Know the difference between the terms of the incident and the reflected light rays. Glass is the transparent material and allows passing of the light through it. Due to the microscopic unevenness of the ground glass, when the light falls on its rough surface gets reflected and scattered in all the directions and does not allow the light to pass through it. During the transmission, the ground glass has the effect of providing the glass the translucent by the scattering of the light and thus blurring the visibility and this type of reflection where the light comes out in various directions is known as the diffused reflection. Refraction of the light is the change in the direction of the light when passed from one medium to another.
