This short document discusses the relationship between the number of waves (N) that can fit in a string of a given length (l) and the wavelength (a) of each wave. It defines the formula N=a/l, stating that the number of waves is equal to the wavelength divided by the length of the string. The document concludes by noting that the number of waves can be calculated using this formula.
