Answer:
Another common example of diffraction is the contrast in sound from a close lightning strike and a distant one. The thunder from a close bolt of lightning will be experienced as a sharp crack, indicating the presence of a lot of high frequency sound.The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc. Diffraction is defined as a process by which light waves break up into dark and light bands or into the colors of the spectrum. Light passing through a narrow opening in the blinds, causing bright and dark shadows and patterns to fall across the floor is an example of defraction.
