What kind of wave is sound and how do the particles move?

Sound waves are classified as Longitudinal waves. This means they move longitude, or sideways. A good way to think of it would be like a slinky moving sideways.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
