Question
A ray of light incident on an equilateral prism at the minimum deviation position. The angle of refraction at the first face (i.e., incident face) of the prism is
Options
A.zero
B.30o
C.45o
D.60o
Solution
Angle of prism, A = r1 + r2
For minium deviation
r1 = r2 = r ∴ A = 2r
Given A = 60o
Hence, r =
