Pumping is the process to achieve population inversion .
In 1895, German physicist Wilhelm Roentgen discovered X-rays. X-rays are electromagnetic in nature and application of X-rays are innumerable.
Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.

First posulate of Special theory of relativity is "The laws of physics take the same form in all inertial frames".
Rate of Stimulated emission depends upon the number of atoms present in the excited state as well as the energy density of photons.
A predictable correlation of the amplitude and phase at any one point with another point is called coherence.
Heisenberg’s uncertainty principle states that: If the x-component of the momentum of a particle is measured with an uncertainty ∆px, then its x-position cannot, at the same time, be measured more accurately than ∆x = ℏ/(2∆px).
CRO or Cathode Ray Oscilloscope displays and measures the electrical signals, time intervals and phase shift between two electrical signals.

The materials which exhibit this property of superconductivity are known as Superconductors.
