Question

The correct sequencing of a
sequencing of angle of incidence, angle of emergence,
o retraction and lateral displacement 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

Answer:

d) 2134

Explanation:

• The angle of incidence is nearly equal to the angle of emergence.
• The angle of refraction is less than angle of incidence because light is travelling from rarer to denser optical medium.
• The lateral displacement remains the same for different angles of incidences.
