Fermat's principle; principle of least time (P. de Fermat):
The principle put by P. de Fermat, which states the path taken through a ray of light among any two points into a system is always the path which takes the least time.
The light passing through a quarter wave plate is analysed by a rotating Nicol prism. It is get that the intensity of the emergent light beam from the rotating Nicol prism becomes
A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase. In comparison to air velocity of sound is main in water,
