The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).
A crystal is a solid whose constituent atoms, ions or molecules are closely packed in a regular fashion with repeating pattern in three dimensions.
Nanotechnology is dealing with the characterization, design, production and various applications of nanostructures and nanosystems.
Nanotechnology have considered as the solution to our smallest to biggest problems. Applications of Nanotechnology are countless.
Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.
Thermodynamics is the branch of physics which deals with heat and other forms of energy and also gives relationships between them.
Drude and Lorentz gave classical free electron theory of metals theory in 1900. Another name for this is Drude –Lorentz theory of metals.
A predictable correlation of the amplitude and phase at any one point with another point is called coherence.
In 1895, German physicist Wilhelm Roentgen discovered X-rays. X-rays are electromagnetic in nature and application of X-rays are innumerable.
In 1960, Maiman constructed the Ruby laser. It is a three-level solid-state laser and is emitting red light of wavelength 694.3 nm.
The process of converting unpolarized light into polarized light is known as polarization.
Most solid materials show elastic behaviour to a lesser or greater extent.
CRO or Cathode Ray Oscilloscope displays and measures the electrical signals, time intervals and phase shift between two electrical signals.
Pumping is the process to achieve population inversion .
Interference of waves occurs when two or more waves overlap at a given point.
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.
