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.
MOMENTUM OR LINEAR MOMENTUM. It is described as "The product of mass and velocity of the body". OR "The quantity of linear motion of a bod
Work: In its technical sense, work is the product of force and distance, and work is done only when a force causes movement. We can see this by the formula: Work = Force x
