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

Neither the speed nor the wavelength of the sound change.

Both the frequency and the wavelength of the sound change.
