A vessel of depth 2 ~d ~cm . is halffilled 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. Ad ( ₁ ₂ ₁+ ₂ )
  2. Bd ( 1 ₁ + 1 ₂ )
  3. C2 d ( 1 ₁ + 1 ₂ )
  4. D2 d ( 1 ₁ ₂ )

Correct answer

B. d ( 1 ₁ + 1 ₂ )

Step-by-step solution

h ^ = d ₁ ₁ + d ₂ ₂ = d ( 1 ₁ + 1 ₂ )
