• water from one place to another.

• sound from one place to another.

• matter from one place to another.

How do sound waves travel through air as a medium?

• Air is pushed away in all directions from the source of the sound.

• Air is displaced in irregular patterns away from the source of the sound.

• Air is displaced in a perpendicular pattern away from the source of the sound.

• Air is pushed back and forth toward and away from the source of the sound.

A trough is

• the resting point of a wave.

• the lowest point of a wave.

• a unit of measurement for a wave.

• the distance between the wave’s crests.

A transverse wave looks like a series of S-shapes because

• of the flexibility of the medium.

• of the way light reflects off the matter.

• of the periodic motion of the matter.

• the person controlling the matter makes it look that way.

A wave pulse is

• the length of a single wave.

• the shape of a single wave.

• the distance a single wave travels.

• a single disturbance that does not repeat.

Rather than troughs and crests, longitudinal waves have

• springs and coils

• horizontals and verticals

• vibrations and pulsations

• compressions and rarefactions
