Why does a diamond shine more than a glass piece cut to the same shape?
A typical diamond is cut into definite angles, so that the light which comes through one surface goes through multiple TIR (Total Internal Reflections). And after so many TIRs, the light comes out through one surface with a much larger intensity. That is why the shape is important in determining the angle.

A small object is placed at the center of the bottom of a cylindrical vessel of radius 3 cm and height 4 cm filled completely with water. Consider the ray leaving the vessel through corner. Suppose this ray and the ray along the axis of the vessel is used to trace the image. Find the apparent depth and the ratio of real depth to apparent depth under the assumptions taken.
