The angle of minimum deviation produced by a thin prism in air is ₁ . If it is immersed in water the angle of minimum deviation is [ a _ g = 3 2 , a _ w = 4 3 ]

Options

  1. A2 ₁
  2. B₁ 2
  3. C₁ 3
  4. D₁ 4

Correct answer

D. ₁ 4

Step-by-step solution

For thin prism, =( -1) A Given, ₁= _ glass _ air = 3 2 and ₂= _ water _ air = 4 3 aligned & ^ = ₁ ₂ _ glass _ water = 3 2 4 3 = 9 8 & ₁ ₂ = ₁-1 ^ -1 = 3 2 -1 9 8 -1 ₂= ₁ 4 aligned
