How would the waves change if the students continued moving the ends of the rope up and down the same
distance but moved the ends faster?

1 answer
If the students continued moving the ends of the rope up and down the same distance (which means the amplitude remains unchanged) but moved the ends faster, this would result in an increase in frequency. As the frequency increases, the wavelength decreases, assuming the speed of the wave remains constant.
Therefore, the correct answer is: The frequency would increase and the wavelength would decrease, but the amplitude would be unchanged.
