A vessel of depth $2 h$ is half filled with a liquid of refractive index $22$ and the upper half with another liquid of refractive index $2$ . The liquids are immiscible. The apparent depth of the inner surface of the bottom of vessel will be :

Options:

Answer:

Solution:

Ans (B)

For near normal incidence,

$h_{a pp} = \frac{h _{a c t u a l}}{( \frac{μ _{in}}{μ _{re f .}} )}$

$∴ h_{a pp a re n t} = \frac{\frac{h}{( \frac{2 2}{2} )} + h}{\frac{2}{1}} = \frac{3 h}{2 2} = \frac{3}{4} h 2$
