A piece of flint glass is lying on top of a container of water (see figure below).
When a red beam of light in air is incident upon the flint glass at an angle of 28°.
What is the angle of refraction in the flint glass?
It is a highly doped p-n junction which is not smashed by high reverse current. The breakdown voltage is made very sharp. In the forward bias, the zener diode do as ordinary diode.
