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)

Both the speed and the wavelength of the sound change.

Explanation: The frequency is set by the source (the guitar) and stays the same across the boundary. The wave speed depends on the medium, so when the wave enters the eardrum its speed changes and, since f = v/λ, the wavelength changes accordingly.
