Describe about Helium-Neon Laser in short.
Helium-Neon Laser:
The first gas laser termed as Helium-Neon (He-Ne) laser (one of the illustrations for four level lasers) was constructed into 1961 year. The most general and inexpensive type of gas laser is generally constructed to operate into the red at 632.8 nm. Into this laser, the active medium is a mixture of He and Ne gas.
Concurrent angular acceleration means angular acceleration at a particular dot instant at t = t 1 mathematically it is given as,

It is the phenomenon of emission of electrons from the surface of metals, when light radiations (Electromagnetic radiations) of suitable frequency drop on them. The emitted electro
Describe how tunneling takes place in reversed bias When junction is reversed biased, p-region moves up with respect to the n-region as a result, filled energy levels on p- sid
Q. Illustrate how do you compute shaft power? Answer:- Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft))/ 60 Torque of a solid shaft is specified by
A particle with mass m = 2:5 is moving along a straight trajectory. The distance covered by a particle is described by the function S(t) = t 3 + 2t 2 , where t > 0 is the time
