The angle of deviation produced by a thin prism when placed in air is ' ₁ ' and that when immersed in water is ' ₂ '. The refractive index of glass and water are 3 2 and 4 3 respectively. The ratio ₁: ₂ is

Options

  1. A1: 2
  2. B2: 1
  3. C1: 4
  4. D4: 1

Correct answer

D. 4: 1

Step-by-step solution

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