In order for John to hear Jill, air molecules must move from the lips of Jill to the ears of John.
I don't agree because molecules don't have to move, but they must transfer the vibration from the sound source through the media
Martina what is the difference between "must not" and "do not have to"?
it's false because movement of material is not involved in a sound wave.A sound wave involves movement of energy from one specific place to another one.
I don't agree because a wave is a transfer of energy and not a transfer of matter so only the waves produced by the motion of the air molecules move.
