A vessel having perfectly reflecting plane botton is filled with water `(mu=4//3)` to depth d. A point source of light is placed at a height h above the surface of water. Find the distance of final image from water surface.

A point source is placed at a depth h below the surface of water (refractive index = mu ). The medium above the surface of water is air from water.

A point source is placed at a depth h below the surface of water (refractive index = mu ). The medium above the surface area of water is air from water.

A point source of light is placed at distance h below the surface of a large and deep lake. What fraction of light will escape through the surface of water?

A cylinderical vessel is filled with water up to height H. A hole is bored in the wall at a depth h from the free surface of water. For maximum range h is equal to

Consider the situation shown in figure. Water (mu=4//3) is filled in a beaker upto a height of 10cm. A plane mirror is fixed at a height of 5 cm from the surface of water. Distance of image from the mirror after reflection from it of an object O at the bottom of the beaker is

A tank is filled with water up to a height H . Water is allowed to come out of a hole P in one of the walls at a depth D below the surface of water. Express the horizontal distance x in terms of H and D .
