Please compute the right solution of the given Problem
Problem-For a source with two frequencies: (wavelength 1 = 4000 nm and wavelength 2 = 2000 nm) of equal intensity, and for an interferometer mirror velocity of 10cm/s.
Part 1- What frequencies, present in the signal from the detector, would be measured in the Fourier Transform of the interferogram (eg the FT of the intensity vs retardation plot)? Make a plot of amplitude vs. frequency and label the frequency from each mode of operation.
I need help to find the frequencies present in the signal.
