Young's double slit

Students in physics investigated the distance between two very closely spaced slits in a double slit interferometer. They also had to measure the wavelength of an unknown source of light and observe the effect that a change in wavelength has on the interference pattern. Students observed the interference pattern produced by a source of white light.
