Three immiscible transparent liquids with uniform refractive indices 3 2 , 4 3 and 6 5 are arranged one on top of another. The depths of the liquids are 3 cm 4 cm and 6 cm respectively. The apparent depth of the vessel is

Options

  1. A10 cm
  2. B9 cm
  3. C8 cm
  4. D7 cm

Correct answer

A. 10 cm

Step-by-step solution

= Real depth (R) Apparent depth Apparent depth = R For vessel, aligned Apparent depth & = R₁ ₁ + R₂ ₂ + R₃ ₃ & = 3 3 / 2 + 4 4 / 3 + 6 6 / 5 & =2+3+5 Apparent depth & =10 ~cm aligned
