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.
Constructive interference is when two or more waves combine, and the amplitude of their resultant wave increases. Destructive interference is when two or more waves combine and the amplitude of their resultant wave decreases. Waves will also diffract. Diffraction is the bending of waves when they hit a barrier. Sound is the result of vibrations in molecules causing the molecules to compress and retract, making sound a longitudinal wave.
