Question

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. (1 point) the frequency of the voice sound wave traveling through the air is the same as when it travels through the door the frequency of the voice sound wave traveling through the air is slower than when it travels through the door. the frequency of the voice sound wave traveling through the air is faster than when it travels through the door. the frequency of the voice sound wave changes with the distance the speaker is from the door. it decreases as it travels across the air in the room.

Explanation:

Frequency of a sound wave is determined by the source (the man's voice here), not the medium it travels through. When sound moves from air to the door (a different medium), the speed (velocity) and wavelength change, but frequency remains constant because it depends on how often the source vibrates. So the frequency in air and through the door is the same.

Answer:

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