Diffraction Grating: A device that consists of many closely spaced slits or grooves that disperses light into its component colors by creating interference patterns.

Order of diffractionformula

Constructive Interference: The phenomenon that occurs when two or more waves combine to produce a wave with a larger amplitude, typically resulting in bright spots in an interference pattern.

Destructive Interference: The phenomenon where two or more waves combine in such a way that their amplitudes cancel each other out, leading to dark spots in an interference pattern.

The order of diffraction refers to the integer that represents the number of wavelengths by which light is out of phase when it passes through a diffraction grating or around an obstacle. It helps classify the resulting interference patterns based on the angles at which constructive or destructive interference occurs, connecting the behavior of light waves to various physical phenomena, including wavelength, grating spacing, and angles of incidence.
