A point source of light S is placed at the bottom of a vessel containg a liquid of refractive index 5/3. A person is viewing the source from above the surface. There is an opaque disc of radius 1cm floating on the surface. The centre of the disc lies vertically above the source S. The liquid from the vessel is gradually drained out through a tap. What is the maximum height of the liquid for which the source cannot at all be seen from above?
