A ray of light is incident on an equilateral triangular glass prism of refractive index 3/2, Calculate the angle through which the ray is minimally deviated in the prism

A.

30.0

B.

37.2

C.

42.0

D.

48.6

Correct answer is B

For the equilateral glass prism A = 600

32Sin(Dm+602)(602)=( Sin Dm+602)0.5Dm=37.2
