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(All India - 2017)

Answer 1

Answer:

C is the answer mate

Answer 2

Answer:

C. p, y, z

Explanation:

It is clear from the diagram:

The angle of incidence is the angle which lies between the normal and the incident ray.

So angle of incidence = p

The angle of emergence is the angle between the emergent ray and the normal.

So angle of emergence = y

The Angle of emergence is angle between the incident ray and the emergence ray.

And Angle of deviation = z

Therefore, the proper sequence is p,y,z
