1. The problem statement, all variables and given/known data Please refer to the attached image. For the first question, The solution calculated the wavelength,λ by taking the whole length of the string (0.75m) as equal to 3λ/2. What I don't understand is, since the string have to bend to produce a wave, how can we just take the displacement of the waves as the length of the string? For question two, What does it mean by "there is no resonant frequency between these two"? What significance does this sentence have?
