Hello I'm a retarded civil student.

I want to know automate determining the wavelength of the tiny oscillation superimposed on the bigger oscillation in the graph. It's plotted as a line but it's discrete evenly spaced points. I think I need to do a discrete fourier transform to get the frequency and amplitude of the two waves right? I'm not quite sure how I calculate wavelength with that...
