Question

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 decreases increases

Explanation:

• Wavelength: When Eli moves his hand back - and - forth more quickly, the distance between consecutive wave crests (wavelength) decreases. This is because a faster hand motion creates more waves in a given length of the spring.
• Frequency: Frequency is the number of waves that pass a given point in a second. A more rapid hand - back - and - forth motion means more waves are created per second, so the frequency increases.
• Energy: The energy of a wave is related to its frequency. Higher - frequency waves (created by the faster hand motion) have more energy.

Answer:

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