6D40.10 - Michelson Interferometer

Code Number:
6D40.10
Demo Title:
Michelson Interferometer
Condition:
Excellent
Principle:
Interference of Light
Area of Study:
Optics
Equipment:
Laser (2 to 5 mw.), Beam Expander, Michelson Interferometer, Small Paper Screen, and Video Camera.
Procedure:

Shine the expanded beam of the laser into the interferometer. Make sure the laser is lined up squarely with the interferometer. When correctly lined up a circular interference pattern will appear on the screen. By changing the path length of the one leg of the interferometer with the control knobs or by just blowing air across one of the mirrors you can observe the fringe shifts. Interference fringes can also be produced using a single mirror.
