A wave moves in a rope with a certain wavelength.A second wave is made to move in the same rope with twice the wavelength of the first wave.The frequency of the second wave is half the frequency of the first wave.

Question

Quizplus · Accepted Answer

The wave speed on a rope is constant for a given tension and mass per unit length. Since wave speed equals frequency times wavelength, doubling the wavelength while keeping the wave speed constant results in halving the frequency.
