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

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.

Answer 1

When a sound wave travels from the air to a person's eardrum, the frequency of the sound wave remains constant, but the speed and wavelength change. Sound travels at different speeds in different media; it moves faster in denser media (like the human body) compared to air. Since the frequency is constant (as it is determined by the source of the sound), the change in speed results in a change in wavelength.

Therefore, the correct response is:

Both the speed and the wavelength of the sound change.
