Which of the following describes the nature of a sound wave:

 Sound energy is a type of energy that is similar to heat, electricity, and light. When we strike a bell, we hear a tremendous ringing noise. Instead of simply listening to the bell, we can now place our finger on it and strike it. Vibration refers to the shaking and movement that occurs as a result of the motion of the body to and fro. This is the sound we can hear; we hear sounds in our daily lives. The sound is the entire process of hearing and being heard.

Transverse waves have medium particle vibrations that are perpendicular to the direction of wave movement, whereas sound waves have medium particle vibrations that are parallel to the direction of wave movement. As a result, sound waves are longitudinal rather than transverse.
