PURPOSE: To show laser light fringes using a Michelson interferometer.
DESCRIPTION: This experiment uses a laser. The system is pre-aligned. The laser light is
expanded by a diverging lens attached to the laser in the photograph. Circular
fringes can be adjusted using the tilting mirror (at the right on the interferometer). The
light exiting the interferometer is focused onto a screen. A video camera
is used to project the
image of the interference fringes seen below:
EQUIPMENT: Michelson interferometer, laser with diverging lens, camera.
