Samuel is trying to hear what is being said on the other side of the door, but the sound of the voices has to pass through a thin door. The sound travels at a velocity of 343 m/s through air, and 560 m/s through the door. The following questions address the frequency and wavelength of the man's voice traveling through air compared to it traveling through the door.

Choose the statement below that BEST describes what happens to the frequency in this scenario.

Q1: The frequency of the voice sound wave traveling through the air is the same as when it travels through the door.

Reason: Frequency is set by the source and does not change when a wave passes into a new medium.

Q2: The wavelength is longer in the door than in the air.

Reason and math: λ = v/f. In air λ_air = 343 m/s ÷ 100 Hz = 3.43 m. In the door λ_door = 560 m/s ÷ 100 Hz = 5.60 m, so the door wavelength is longer.
