Which of the following best describes a longitudinal wave?

Group of answer choices

a type of wave that encounters an impenetrable barrier

a type of wave where the transmitted wave will move in a different direction than the incident wave

a type of wave where the movement of the medium is perpendicular to the direction of the energy propagation

a type of wave where the particles of the medium move parallel to the direction of the wave

1 answer

The option that best describes a longitudinal wave is:

a type of wave where the particles of the medium move parallel to the direction of the wave.

In longitudinal waves, such as sound waves, the particles of the medium oscillate back and forth in the same direction as the wave is traveling.
