In a thin prism of glass (refractive index 1.5), which of the following relations between the angle of minimum deviations dm and angle of refraction r will be correct?
A
dm = r
B
dm = 1.5r
C
dm = 2r
D
dm = 
Answer
dm = r
Explanation
Solution
For minimum deviation r = 
̃ A = 2r
dm = (m – 1)A = (1.5 – 1) × 2r
