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 ... Webpassing through the grating. Since the only unknown is this equation is the slit spacing d you can easily solve for it. Although a CD is not really a diffraction grating, after all the light bounces off of the CD, it does not pass through it, the CD acts like a diffraction grating because the reflected light undergoes constructive and destructive
