What is the principle of operation of a diffraction grating?
October 29, 2020 | Education|
The operation of a diffraction grating is based on the phenomenon of diffraction of a light wave, which, passing through a system of transparent and opaque regions, is divided into separate beams of coherent light. They undergo stroke diffraction. And at the same time they interfere with each other. Each wavelength has its own diffraction angle, so white light is decomposed into a spectrum.
