As a longitudinal wave moves through a medium, the particles of the medium

• vibrate in a path parallel to the path of the wave

• vibrate in a path perpendicular to the path of the wave

• follow the wave along its entire path

• do not move

Two light rays will interfere constructively with maximum amplitude if the path difference between them is:

• one wavelength

• one-half wavelength

• one-quarter wavelength

• one-eighth wavelength

The rate at which any part of a wave travels from one place to another determines the wave's:

• propagation velocity

• period

• amplitude

• frequency
