speed

Answer 1

When one student moves the jump rope up and down faster, the frequency of the wave increases. Frequency refers to the number of waves that pass a given point in one second. If the student moves the rope faster, they create more waves in the same amount of time, thus increasing the frequency.

So, the correct answer is:

Frequency
