okay the question i got was asking the lengths of the first, second, and third waves of a standing wave, of a string that is fixed at both ends. the strings length is 2.38 meters. Ive already figured out the three lengths, being 4.76, 2.38, and then 1.59. how would i figure out the frequency of the third wavelength, if the second is 54Hz???
