Single and Double Slit Set of 3, 1 Each

The Single and Double Slit Set of 3 by United Scientific contains three 50 x 50 mm diffraction slides: a single slit slide with five widths from 0.1 to 1.6 mm and two double slit slides that vary either slit width or slit separation. Physics teachers use the set with a laser pointer (not included) to demonstrate diffraction, interference, and the wave nature of light.
