Find the height $h$ of the pits on a CD (Fig. 25.6a). When the laser beam reflects partly from a pit and partly from land (the flat aluminum surface) on either side of the "pit", the two reflected beams interfere destructively; $h$ is chosen to be the smallest possible height that causes destructive interference. The wavelength of the laser is $780 \mathrm{~nm}$ and the index of refraction of the polycarbonate plastic is $n=1.55$.
