Verified Solution • 2025–26 Session moderate

A vessel of depth 2h is half filled with a liquid of refractive index

2 \sqrt{2}

and the upper half with another liquid of refractive index

\sqrt{2}

. The liquids are immiscible. The apparent depth of the inner surface of the bottom of vessel will be :

Accepted Answer

D =

\frac{t_{1}}{μ_{1}} + \frac{t_{2}}{μ_{2}}

=

\frac{h}{\sqrt{2}} + \frac{h}{2 \sqrt{2}}

=

\frac{3}{4} h \sqrt{2}
