At 26.4 Hz, there were two nodes on the line, plus those at each end. How did the pattern of nodes change as the resonant frequencies increased? Select all that are appropriate.

more than 1 possible solution

At each successively higher resonant frequency there was one more node on the string.

The spacing between nodes is 1/2 the wavelength at that frequency.

The spacing between nodes is inversely proportional to the frequency

The product of frequency and wavelength is the speed of the wave.
