Four students at a concert notice a balloon near the large speakers moving slightly towards, then away from the speaker during the low-frequency passages. The four students explain this phenomenon .
Student A: The wave is a longitudinal wave because sound is made by regions of air being slightly more compressed followed by regions that are slightly less compressed.
Student B: The wave is a transverse wave because sound is made by regions of air being slightly more compressed followed by regions that are slightly less compressed.
Student C: The wave is a longitudinal wave because sound is made by regions of air moving perpendicular to the sound wave.
Student D: The wave is a transverse wave because sound is made by regions of air moving perpendicular to the sound wave
