WebMar 7, 2024 · These act as a diffraction grating. Normally this is a reflection grating, but one can make a transmission grating by removing the metal layer (easiest in recordable … Webexamples of diffraction are those involving light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern we see when looking at a disk. Diffraction in the atmosphere by small particles can cause a bright ring to be visible around a bright light source like the sun or the moon.
