How It Is Used
The sodium lamp is connected to the unit and the mains switched on. The ballast supplies a high-voltage pulse to start the arc and then limits the lamp current for steady, flicker-free running. The lamp is used as the monochromatic source in Newton’s rings and Michelson interferometer experiments.
