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?(adsbygoogle = window.adsbygoogle || []).push({});

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?
