Question

answer the following question​

Answer 1

Explanation:

3/2 =[ sin(60°+d)/2]/sin(60°/2)

1.5 = sin(60°+d)/2/sin30° [As A = d]

0.75 = sin(60°+d)/2

30°+d/2 = 48.6

d = (48.6 - 30)*2

d = 37.2°

i + e = A + d [e = angle of emergence]

In case of Dmin. , i = e

2i = A+d

i = (A+d)/2 = (60+37.2)/2

= 48.6
