Question

The correct sequencing of angle of incidence, angle of emergence, angle of refraction and lateral displacment shown in the following diagram by digits 1,2,3 and 4 is :

A. 2,4,1,3
B. 2,1,4,3
C. 1,2,4,3
D. 2,1,3,4

Answer 1

From the knowledge of theory, we know
2 represents angle of incidence
1 represents angle of emergence
4 represents angle of refraction, and
(3) represents lateral diplacement.
