A transparent cube of 15 ~cm edge contains a small air bubble. Its apparent depth when viewed through one face is 6 ~cm and when viewed through opposite face is 4 ~cm . The refractive index of material of cube is

Options

  1. A2.0
  2. B1.5
  3. C1.6
  4. D2.5

Correct answer

B. 1.5

Step-by-step solution

Here, real depth, x=15 ~cm apparent depth, y=6+4=10 ~cm = x y = 15 10 =1.5
