2. How does sound travel from a loud speaker to a person listening on the other side of the room.
a)
The speaker vibrates which causes air particles to vibrate. These vibrations get passed on from particle to particle till they reach the ear.
b)
Sound particles are given out by the speaker, they travel through the air until they reach the ear.
c)
It just does. Sound magically appears in your head
d)
Psychic energy travels from the loud speaker to the ear through the particles in the air.
