Pumping is the process to achieve population inversion .
Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
In 1895, German physicist Wilhelm Roentgen discovered X-rays. X-rays are electromagnetic in nature and application of X-rays are innumerable.
Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.
W. L. Bragg gave a simple explanation for the study of crystal structure by using the phenomenon of diffraction and name it is as Bragg’s law.
The process of converting unpolarized light into polarized light is known as polarization.
Pumping is the process to achieve population inversion .
A predictable correlation of the amplitude and phase at any one point with another point is called coherence.
Magnetic Hysteresis Curve represents the relation between magnetizing force (H) and magnetic flux intensity for ferromagnetic material.
The materials which exhibit this property of superconductivity are known as Superconductors.
CRO or Cathode Ray Oscilloscope displays and measures the electrical signals, time intervals and phase shift between two electrical signals.
Semiconductors are materials that have conductivity between conductors and insulators.
