A vessel contains water up to a height of 20 cm and above it an oil up to another 20 cm. The refractive indices of the water and the oil are 1.33 and F30 respectively. Find the apparent depth of the vessel when viewed from above.

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

An object is placed at the bottom of a tank filled with liquid of refractive index 1.6. If the actual depth of the tank is 10 cm, what will be the apparent depth of the object?

A vessel of height 2d is half-filled with a liquid of refractive index sqrt(2) and the other half with a liquid of refractive index n. (The given liquids are immiscible). Then the apparent depth of the inner surface of the bottom of the vessel (neglecting the thickness of the bottom of the vessel) will be
