Question

Study the following ray diagram:
In this diagram, the angle of incidence, the angle of emergence and the angle of deviation respectively have been represented by
(A) y, p, z
(B) x, q, z
(C) p, y, z
(D) p, z, y

Answer 1

The angle of incidence, the angle of emergence and the angle of deviation respectively have been represented by (C) p, y, z

Explanation:

The image given in the question is attached below.

• The ray that falls on the mirror is called incident ray.
• The ray that is emerged from the mirror is called emerged ray.
• The line that is draw perpendicular to the object at the point of incident and reflection is called normal line.
• The angle between incident ray and normal line is called angle of incident.
• The angle between emerged ray and normal line is called angle of emergence.
• The emerged ray is bent at an angle with respect to incident ray. This angle is called as angle of deviation.
