The refractive index of a transparent liquid filled in an equilateral hollow prism is 2 . The angle of minimum deviation for the liquid will be _______ ° .

Step-by-step solution

For minimum deviation in a prism, μ = sin D m i n + A 2 sin A 2 The value of minimum deviation is ⇒ 2 = sin D m i n + 60 ° 2 sin 30 ° ⇒ 1 2 = sin D m i n + 60 ° 2 ⇒ 45 ° = D m i n + 60 ° 2 ⇒ D m i n = 30 °
