If two of the wavelengths of standing waves on a 12m rope secured at both ends are 2m and 1m, which of the following COULD NOT be a standing wave wavelength on the same rope with the same tension?

4m, 2.5m, 1.5m, or 67cm.


2L/n=lamda



I said 2.5m because this does not give an natural number solution to the formula. Is this correct?

Correct. It would not be a fundamental evenly divisible into the length.
