Experiments to determine the relative intensity of light scattered at various angles from several materials were performed. Various target materials were mounted on an optical bench and illuminated by a Spectra Physics 116 gas laser. The targets were rotated through various angles with respect to the optical bench, and the distance between the detector and target was varied to record a constant voltage reading on a 555 oscilloscope. Different graphs showing isointensity lines for various angles of incidence as well as graphs showing the percent of intensity reflected as a function of distance were then plotted. Author
