PIRA Classification: 6D40.10

Description: A Michelson interferometer is shown to the class. The laser (which is carefully aligned) is turned on while the initial position of the micrometer is read. The number of fringes is counted while the micrometer is slowly turned. The final position of the micrometer is read again. If you wish, a tunable laser (red, orange, orange-yellow, yellow, and green) can be used to demonstrate the wavelength dependence of the pattern.
