Question

another way maya gets a more intense workout is by moving her arms faster to make the waves crests closer together. in this graph, the blue line models a wave maya created with a battle rope earlier in her workout. the orange line models another wave she creates by moving her arms faster.

complete the sentences.
when maya moves her arms up and down faster, she decreases the ▼ and increases the ▼ of the wave. as a result, mayas workout is more intense, which means the energy of the waves she creates ▼.

Explanation:

• Wavelength: Wavelength is the distance between successive crests (or troughs) of a wave. When Maya moves her arms faster, the crests get closer together, so the wavelength decreases.
• Frequency: Frequency is the number of waves that pass a given point in a certain time. Faster arm - movement means more waves are created in a given time, so the frequency increases.
• Energy: The energy of a wave is related to its frequency. Higher - frequency waves (for a given type of wave, like the rope waves here) have more energy.

Answer:

When Maya moves her arms up and down faster, she decreases the wavelength and increases the frequency of the wave. As a result, Maya's workout is more intense, which means the energy of the waves she creates increases.
