1. Unit 4 - Energy
Learning Target 4.2 – Be able to compare & contrast Transferse Waves versus Longitudinal (compression) Waves

2. Transverse Waves
A transverse wave is one in which the oscillations are perpendicular to the direction of travel.
Notice, in the image below, the wave is moving left-to-right but it is oscillating in the up-and-down direction.

3. Another Example of a Transverse Wave

4. Another Example of a Transverse Wave

5. Longitudinal (compression) Waves
Longitudinal waves produce oscillations parallel to the direction of travel. (longitudinal waves are also called compression waves)

6. Another Example of a Longitudinal Wave
The wave in the image below has oscillations parallel to the direction of travel.
The wave is moving left-to-right.
The wave is also compressing and relaxing left-to-right
