Why radio waves diffract around buildings?
Diffraction of radio waves The phenomenon of bending of waves around the corners of an obstacle or opening placed in its path is called diffraction.The phenomenon is found to be prominent when wavelength of the waves is comparable with the…

Different types of rectifiers and their applications in daily life
What is Rectification? The conversion of alternating current into direct current is called rectification. Semiconductor diodes are extensively used for this purpose. How many types of rectification ? There are three common types of rectification: Half-wave rectification Full-wave rectification Full…

State the Pauli Exclusion Principle
According to Pauli Exclusion Principle, No two electrons can have samples values of the quantum numbers n, l,ml and ms or they can not have all these quantum numbers similar; at least one of the four numbers which are strictly required to Specify…

Planck’s radiation law derivation
Rayleigh-Jeans law and Wien’s formulae were failed to solve the problem of distribution of spectral radiance among various wavelengths in cavity radiations because these formulas were based upon the classical theory. Planck’s quantum theory of radiation In 1900, Max Planck…

Why diffraction grating have closely spaced rulings?
A diffraction grating is a glass plate having a large number of close parallel equidistant slits mechanically ruled on it.A diffraction grating is used to study the diffraction effects of light. Since the phenomenon of diffraction is found to be…

Interference of Light Examples
Interference of light is defined as: “When two or more light waves having the same frequency, same wavelength and same amplitude meet together in a medium at a point, they cancel or enhance the effect of each other at that…
