The sound of a plucked guitar string travels through the air and strikes the eardrum of a person in the same room. How does the sound wave change when it transfers from the air to the person’s eardrum?(1 point)

Question

Responses

Both the speed and the wavelength of the sound change.
Both the speed and the wavelength of the sound change.

Both the frequency and the wavelength of the sound change.
Both the frequency and the wavelength of the sound change.

Neither the speed nor the wavelength of the sound change.
Neither the speed nor the wavelength of the sound change.

Neither the frequency nor the wavelength of the sound change.

Answer 1

When a sound wave travels from air into a medium like a person's eardrum, the speed of sound generally changes because sound travels at different speeds in different media. Since the frequency of a sound wave remains constant as it enters a new medium, the change in speed leads to a change in wavelength.

Thus, the correct response is:

Both the speed and the wavelength of the sound change.
