Question

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

Explanation:

When Eli moves his hand back and forth a greater distance in a longitudinal wave (like in the spring toy), the amplitude (in a longitudinal wave, related to the compression and rarefaction intensity - here, how much the spring coils are compressed or pulled apart more) of the wave increases. And according to the relationship between wave energy and amplitude (for mechanical waves, energy is proportional to the square of the amplitude), as the amplitude increases, the energy of the wave increases.

Answer:

The amplitude of the wave increases. As a result, the energy of the wave increases.
