The main idea of a pendulum wave is to observe how once the pendulums of different lengths are released, they immediately have different frequencies. From our studies of simple harmonic motion, the pendulum wave is made up of many pendulums that are undergoing simple harmonic motion. We know that the period and the frequency is not affected by the mass of the balls. What each wave is affected by is the length of the string from which each ball is hanging. This is why the frequency of each pendulum is different than the one next to it.

String Length:
the length represents the wavelength of the pendulum
the lengths will be found using a recursive formula
the first length will be determined using a chosen frequency
the length of each pendulum includes the start of the string to the center of mass of the ball
Frequency:
the number of waves that pass a point in one second
it is controlled by the wavelength (the length of the string)
the number of oscillations needs to be chosen in order to then use a recursive formula to calculate the lengths of each
the first frequency will be determined by dividing the number of chosen back and forth swings in 30 seconds by 30.
