In a longitudinal wave, the particles of matter in the medium vibrate by pushing together and moving apart. In a transverse wave, on the other hand, the particles of matter in the medium vibrate by moving back and forth.
Which of the following is true about the movement of the particles in longitudinal and transverse waves?
A.
The particles in longitudinal waves travel perpendicular to the direction of the wave, whereas the particles in transverse waves travel parallel to the direction of the wave.
B.
The particles in longitudinal waves and the particles in transverse waves both travel perpendicular to the direction in which the wave is traveling.
C.
The particles in longitudinal waves travel parallel to the direction of the wave, whereas the particles in transverse waves travel perpendicular to the direction of the wave.
D.
The particles in longitudinal waves and the particles in transverse waves both travel parallel to the direction in which the wave is traveling.
