Principle of Nicol Prism Engineering Physics B.Tech 1st Year
What is Nicol Prism? Nicol prism is an optical device which is used for producing and analyzing plane polarized light in practice. Principle of Nicol Prism: Nicol Prism is based…
Phenomena of Double Refraction
Double refraction is an optical property in which a single ray of unpolarized light when entering an anisotropic medium is split in two rays, each following a different direction. One…
Rayleigh Criterion
The Rayleigh Criterion: The Rayleigh Criterion specifies the minimum separation between two light sources that may be resolved into distinct objects. The Rayleigh criterion is the criterion for the minimum…
Dispersive Power
Definition: Dispersive power is defined as the power of a transparent medium to separate different colors of light by refraction as measured by the difference in refractivity for two specified…
Grating Spectrum
Grating Spectrum: The diffraction pattern formed with a grating is known as a grating spectrum. A diffraction grating is an optical component with a periodic structure, which splits and diffracts…
Diffraction Grating
What Is Diffraction Grating ? A diffraction grating is made by making many parallel scratches on the surface of a flat piece of some transparent material. A diffraction grating disperses…
