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?

The correct response is:
The frequency would increase and the wavelength would decrease, but the amplitude would be unchanged.
When the students shake the ends of the rope faster while keeping the movement distance (amplitude) the same, the frequency of the waves increases, leading to a shorter wavelength.
