Experimental Physics I & II "Junior Lab"


Michelson Interferometer


The objective of this experiment is to demonstrate the interference pattern obtained from combining coherent monochromatic light beams using a Michelson interferometer setup. You will ultimately derive the wavelength of the light source from your measured interference pattern.
