What is a transverse wave?

• A wave in which particles of the medium move in a direction parallel to the direction of wave propagation.

• A wave in which particles of the medium move in a direction perpendicular to the direction of wave propagation.

• A wave that requires a medium to travel through.

• A wave that does not require a medium to travel through.

A wave in which the vibration of the medium is parallel to, or in the same direction as, the direction in which the wave travels is called a(n) _______________.

• longitudinal wave

• transverse wave

• surface wave

• electromagnetic wave

When a longitudinal wave carries energy through a spring, the area where the coils of a spring are closer together than they would be in the rest position is called a(n) _______________.

• compression

• rarefaction

• oscillation

• amplitude
