Q. Briefly explain working of Michelsons Interferometer?
Michelson designed an instrument for the measurement of wavelength of sodium light, thickness of thin film and for many applications. The instrument is based on principle of interference of light known as Michelson's Interferometer.
It is based on principle of interference of light by the way of division of amplitude. According to this the incident beam is divided into two parts and sent into two perpendicular directions and brought back together by using plane mirror to interface each other.
Uniformity principle (E.P. Hubble): The principle that the laws of physics here & now are not distinct, at least qualitatively, from the laws of physics in previous or future
The waves which needs medium for their propagation are known as mechanical waves. Example : Waves on string and spring, waves on water surface, sound waves, seismic waves.
Electrons and holes in semi-counductor Metals have free electrons available in conduction band for conduction of electric current. As the valence band overlaps the conduction b
