1. What is the difference between ψ = Amod(t) cos (wavt)and the simple harmonic oscillator? 3. A. The amplitude is time dependent B. The amplitude,Amod , is twice the amplitude of the simple harmonic oscillator, A. C. The oscillatory behavior is a function of ? instead of the period, T. I'm not sure what the difference is. I thought that the equations are similar but that was incorrect.
