Question

A container contains a liquid with refractive index of 1.2 up to a height of 60 cm and another liquid having refractive index 1.6 is added to height H above first liquid. If viewed from above, the apparent shift in the position of bottom of container is 40 cm. The value of H is ______ cm.
(Consider liquids are immisible)

TestHub · Accepted Answer

y = apparent depth of bottom 1 y ​ = 1.6 H ​ + 1.2 60 ​ Shift = 40 H + 60 − y = 40 H + 60 − 1.6 H ​ − 1.2 60 ​ = 40 16 6 ​ H = 30 H = 80 cm
