Refer to the figure for heterodyne interferometer. Complete the figure with values for fl, f2, Af calculated and indicated at the appropriate place based on the following: a. 633nm laser used (velocity of light is 3x10 m/s) b. Zeeman splitting causes a frequency difference of 2MHz between the beams c. The external cube corner reflector vibrates with a frequency of 500KHz and 2 peak to peak amplitude (note: redraw the figure roughly and give your answers. Show calculations as well) Beam splitters.
