Longitudinal Waves

Ms. K

What are longitudinal waves?

Longitudinal waves are waves in which the particles vibrate back and forth in compressional pulses.

Real World Example!

Sound waves are one type of longitudinal waves. Speakers will make sounds that then travel in longitudinal waves through either the medium of water, air, or a solid.

Fun Fact

Longitudinal waves are classified as mechanical waves. This means that they need a medium in order to travel. In space waves travel in vacuums since there are no mediums so longitudinal waves can't travel in space unless a medium is brought there. Due to this you will never hear sound in space!
