A beam of monochromatic light is incident on one face of an equilateral prism, the angle of incidence being 55 0 . If the angle of emergence is 46 0 then the angle of minimum deviation is –
Text Solution
Verified by ExpertsThe correct answer is:
B
A = 60 0 ; i = 55 0 ; e = 46 0
∴ i + e = A + δ
55 0 + 46 0 = 60 0 + δ
⇒ δ = 41 0 δ min < δ
