Question

UA 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, pand z (b) x, q and z (c) p. y and z (d) p, z and y​

Answer 1

Explanation:

It is clear from the diagram,

Angle of incidence =p

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

Angle of emergence =y

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

And Angle of deviation=z

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

So the proper sequence is p,y,z
