What is grating in physics? - Quora

in physics, a diffraction grating is an optical component with a periodic structure, which splits and difracts light into several beams travelling in different directions. The emerging coloration is a form of structural directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.

 Resolving Power of a Plane Transmission Grating

Resolving Power of a Plane Transmission Grating

Resolving power of a plane transmission grating. The capacity of an optical instrument to show separate images of very closely placed two objects is called resolving power. The resolving power of a diffraction grating is defined as its ability to form separate diffraction maxima of two closely separated wave lengths.
