In the textbook, it said that standing waves only occur at the resonant frequencies of the medium. I don't understand why.
My understanding of standing waves is that it is when the medium length (slinky) is a multiple of 1/2 of the wavelength. This allows the reflected wave to interfere with the original wave creating the standing waves. What does this have to do with resonant frequency?
Thanks
