Question 148: Ray Optics

Question

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 = ${{{t_1}} \over {{\mu _1}}} + {{{t_2}} \over {{\mu _2}}}$
= ${h \over {\sqrt 2 }} + {h \over {2\sqrt 2 }}$
= ${3 \over 4}h\sqrt 2 $

Answer

${h \over {\sqrt 2 }}$

Answer

${h \over {3\sqrt 2 }}$

Answer

${3 \over 4}h\sqrt 2 $

Answer

${h \over {2\left( {\sqrt 2  + 1} \right)}}$
