The man in the red shirt has a voice frequency of 100 Hz. Mathematically, how does the wavelength compare as the voice travels

through the air, versus through the door. (1 point)
The wavelength is longer in the air than it is in the door
The wavelength is the same in the air and in the door.
The wavelength is longer in the door than in the air
Not enough information is provided to solve.

Not enough information is provided to solve. The wavelength of sound waves depends on the speed of sound in the medium, which is different for air and door materials.
