A vessel having perfectly reflecting plane bottom is filled with water (μ=4/3) to a 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.
Water level is maintained in a cylindrical vessel up to a fixed height H. The vessel is kept on a horizontal plane. At what height above the bottom should a hole be made in the vessel so that the water stream coming out of the hole strikes the horizontal plane at the greatest distance from the vessel?
A tank is filled with water upto a height H. Water is allowed to come out of a hole P in one of the walls at a depth h below the surface of water (see figure). Express the horizontal distance X in terms of H and h.
A point source S is placed at a height h from the bottom of a vessel of height H(<h). The vessel is polished at the base. Water is gradually filled in the vessel at a constant rate α m3/s. The distance d of image of the source after reflection from the mirror, from the bottom of the vessel will be varies with time t as :
