Problem: A laser beam of wavelength 632.8 nm shines at normal incidence on the reflective side of a compact disc. The tracks of tiny pits in which information is coded onto the CD are 1.60 µm apart.
Part I: For what nonzero angles of reflection (measured from the normal) will the intensity of light be maximum?
