An object lying 100 cm inside water is viewed normally from air. If the refractive index of water is 4 3 , then the apparent depth of the object is

Options

  1. A100 cm
  2. B50 cm
  3. C25 cm
  4. D75 cm

Correct answer

D. 75 cm

Step-by-step solution

Real depth =100 ~cm , = 4 3 Apparent depth = Real depth = 100 3 4 =75 ~cm
