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? (1 point)
• frequency
O wavelength
• amplitude
o speed
The quantity of the wave that will increase when the student moves the jump rope faster is the frequency. Frequency is defined as the number of complete wave cycles that occur in a given time interval. When the student moves the rope faster, they are able to create more wave cycles in the same amount of time, thus increasing the frequency of the wave.
Use the table to answer the question.
