SUMMARY
The discussion focuses on determining possible standing wave wavelengths on a 12-meter rope secured at both ends, with established wavelengths of 2 meters and 1 meter. The key conclusion is that the wavelengths must be integer multiples of half the wavelength, leading to valid wavelengths of 2m, 1m, and others derived from this principle. The incorrect option identified is 67 cm, as it does not satisfy the condition of being an integer multiple of half a wavelength. The calculations confirm that only specific lengths can produce standing waves on the rope.
