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.
2. The dipole in problem is removed and the space between plates is filled with Cu of conductivity σ (look up the value). (a) Derive an expression for the current density betwee
how faster ultrsonic waves will travel in solids.
A single-phase transformer has 2400 turns on the primary and 600 turns on the secondary. Its no-load current is 4A at a power factor of 0.25 lagging. Suppose the volt drop
why laser show beat phenomenon while LIGHT do not.

The device which changes chemical energy into electrical energy is called as electric cell. Battery is a host of constant emf but not constant current.
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
