Question

eli moves his hand back and forth slowly, creating a longitudinal wave in the spring toy.then, he moves his hand back and forth more quickly. this creates a wave with more energy.describe what happens when eli moves his hand back and forth more quickly. complete the sentences.the wavelength of the wave ▼ and the frequency of the wave ▼.as a result, the energy of the wave ▼.

Explanation:

When the hand moves faster, more wave cycles are created in the same space, so the distance between consecutive compressions (wavelength) decreases. Frequency is the number of cycles per second, so faster hand motion increases frequency. Wave energy is directly related to frequency; higher frequency means higher energy.

Answer:

The wavelength of the wave decreases and the frequency of the wave increases.
As a result, the energy of the wave increases.
