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.
A point charge q is imbedded at the center of a sphere of linear dielectric material (with susceptibility and radiusR). Find the electric field, the polarization, and the bound cha
The lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic field.
A spacecraft design similar to GEOSAT proposes to use passive gravity-gradient stabilization for pitch attitude control (motion about the y-axis). The satellite consists of a tip

The average energy needed to release a nucleon from the nucleus is known as binding energy per nucleon. Binding energy per nucleon diffrence Stability of nucleus
Do fibers have losses? Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in.
a) Heat produced is directly proportional to the square of the current passing by a conductor. b) This effect is produced because of collision of free electrons with positive io
