A vessel of depth 2 ~d ~cm is half filled with a liquid of refractive index ₁ and the upper half with a liquid of refractive index ₂ . The apparent depth of the vessel seen perpendicularly is

Options

  1. A( ₁ ₂ ₁+ ₂ ) d
  2. B( 1 ₁ + 1 ₂ ) d
  3. C( 1 ₁ + 1 ₂ ) 2 ~d
  4. D( 1 ₁ ₂ ) 2 ~d

Correct answer

B. ( 1 ₁ + 1 ₂ ) d

Step-by-step solution

Apparent depth = d / ₁+ d / ₂
