Determining the wavelength of the light of an He-Ne laser using a Michelson interferometer
$1.00
In the experiment P5.3.4.2, the wavelength of an He-Ne laser is determined from the change in the interference pattern when moving an interferometer mirror using the shifting distance Δs of the mirror. During this shift, the interference lines on the observation screen move. In evaluation, either the interference maxima or interference minima passing a fixed point on the screen while the plane mirror is shifted are counted.
