Photons and gravity: It is observed that light is affected by gravity. We can recognize the gravitational behaviour of light from the fact that although a photon has zero rest mass, it interacts with electrons as though it has inertial mass.
Gravitational Red shift: As we know that an interesting astronomical effect because of the gravitational behaviour of light i.e., the frequency associated with a photon moving towards earth enhances and the frequency of a photon moving away from earth should reduce.
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
Angle of Minimum Deviation: The angle of deviation has least value when incident ray and emergent ray make equivalent angle with the normal. The value of angle of deviation is
