A diffraction grating is a optical material or device that is usually designed to break up white light into the various colors of the visible spectrum.laze angles are used to concentrate a diffraction grating output on a certain band region of the light spectrum. This is done to obtain a maximum resolution in a particular band of light known as the Blaze wavelength.
Diffraction Definition. Refraction is the bending of light or sound waves that moves from one medium to another and a change in speed is forced. Refraction creates optical phenomenon and illusions. Diffraction of Light is bending of the light waves around an object.efraction is the bending of light or sound waves that moves from one medium to another and a change in speed is forced.
