Question

to get a more intense workout, maya needs to transfer more energy to the battle ropes. one way maya does this is by moving her arms farther up and down to make the waves in the ropes taller. in this graph, the blue line models a wave maya created with a battle rope earlier in her workout. the orange line models a wave maya creates by moving her arms farther up and down. describe what happens when maya moves her arms farther up and down. complete the sentence. maya transfers more energy to the rope and _______________ of the wave. increases the frequency decreases the frequency increases the amplitude decreases the amplitude

Explanation:

The amplitude of a wave is the maximum displacement from the rest position. In the graph, the orange line (when Maya moves arms farther up and down) has a greater maximum displacement (taller wave) compared to the blue line. Energy transferred to a wave is related to its amplitude (higher amplitude means more energy transferred). Frequency is related to how many waves pass a point in a given time - the wavelength (distance between two consecutive crests or troughs) of both waves (blue and orange) seems similar (so frequency which is \(f=\frac{v}{\lambda}\), assuming wave speed \(v\) in the rope is constant, and \(\lambda\) (wavelength) is same, frequency \(f\) is same).

Answer:

increases the amplitude
