in a longitudinal wave, how do particles move? *\nup and down (perpendicular with the direction of the wave)\nback and forth (parallel to the direction of the wave)\nin a circle
Answer
Brief Explanations:
In a longitudinal wave, particles move parallel to the direction of the wave propagation. This is in contrast to transverse waves where particles move perpendicular to the wave direction.
Answer:
Back and forth (parallel to the direction of the wave)
