Question

In the following ray diagram the correctly marked angles are:; A. i and D; B. A and D; C. i, Le and D; D. r, A and D(All India - 2016)

Answer 1

Answer:

a

Explanation:

Answer 2

In the following ray diagram, the correctly marked angles are: r, A and D.

Option D) r, A and D

• r = angle of refraction
• A = angle of emergence
• D = angle of deviation.
• r = the angle between the refracted ray and the normal drawn at the point of incidence.
• A = the angle between the normal and the emergent ray is called the angle of emergence.
• D = the angle between the direction of refracted and the normal ray is called the angle of deviation.
