WebThe diffraction grating is an immensely useful tool for the separation of the spectral lines associated with atomic transitions. It acts as a super prism, separating the different colors of light much more than the dispersion effect in a prism. ... the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar ... 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. WebThe most striking examples 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 seen when looking at a disk.
