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

उत्तर
Angle p is the angle of incidence since this angle is formed between the incident ray and the normal.
Angle y is the angle of emergence as it is formed between the emergent ray and the normal.
and angle z is the angle of deviation as it is formed between the emergent ray and the incident ray.
Hence, the correct answer is p, y, z
