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.
(a) diffraction and polarization (b) interference and diffraction (c) polarization and reflection (d) refrac-tion and diffraction (e) reflection and interference 10. When you receive a chest x-ray at a hospital, the x-rays pass through a set of parallel ribs in your chest. Do your ribs act as a diffraction grating for x-rays? (a) Yes.
