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???

if the wavelength is half and the speed of the wave is constant then the frequency is double.
distance = rate * time
wavelength = speed * period
period = 1/frequency
wavelength = speed /frequency

thanks, that helped a lot!
