I am doing a Michelson interferometer lab which instructs me to use the equation Fb=(Fl*v)/c, where Fb is the beat frequency, Fl is the frequency of the laser, and v is the velocity of a oscillating mirror. The interferometer has one stationary mirror and a mirror that is mounted on a speaker that oscillates from a signal provided by a function generator. I'm trying to find the origin of the Fb=... equation.(adsbygoogle = window.adsbygoogle || []).push({});
