What is the pattern for predicting standing waves if you know the fundamental frequency? Odd frequencies All whole number multiples of the fundamental (i.e. if the fundamental is 0.42, then 0.84, 1.26, 1.68, etc.) Frequencies near the fundamental (i.e. if the fundamental is 0.42, then 0.35 and 0.49 etc. should work). Even frequencies Doubling each frequency (i.e. if the fundamental is 0.42, then 0.84, 1.68, etc.) Note - there is one obvious different frequency between this choice and (a) and if you think either of these is the answer, I suggest you try that frequency
