Two students hold the ends of a jump rope. One student moves the jump rope up and down, making a wave. Then, the student moves it faster. Which quantity of the wave will increase?

Answer 1

When the student moves the jump rope up and down faster, the frequency of the wave increases. The frequency is defined as the number of wave cycles that pass a point in a given time period, typically measured in hertz (Hz). As the speed of the motion increases, more wave crests and troughs are produced in the same time interval, thus increasing the frequency of the wave. Therefore, the quantity of the wave that will increase is the frequency.
