Plotting the algebraic sum by itself, we can definitely see the "beats". This curve is periodic with period = _________ and frequency = ______. Its maximum amplitude is ______.

Check to see that your results support the mathematical fact that the frequency of the beat curve (blue) should be the difference in the frequency of the two individual curves (red frequency - green frequency).
