Answer 1

When the student moves the jump rope up and down to create a wave, and then moves closer, the quantity that will decrease is the wavelength.

As the two students get closer together, the distance between successive crests (or troughs) of the wave will decrease, resulting in a shorter wavelength, assuming the frequency of the wave remains constant.

So, the correct answer is wavelength.
