Transverse & Longitudinal Waves
Transverse Waves
Transverse Waves
Here are some examples of transverse waves:
Moving springs
Moving springs
- Waving/moving the coils of a spring will make the coils move up and down as the wave passes.
- They then return to their original position after the wave has passed.
- This shows that a wave moves without transferring matter because the spring coils do not travel along with the wave.
Mexican wave
Mexican wave
- A “Mexican wave” at a sports event is an example of a transverse wave.
- The wave spreads around the stadium as the people stand up and sit down one after the other (at right angles to the direction of the people’s motion).
Corks bobbing
Corks bobbing
- A cork bobbing on the water shows how a transverse wave works.
Longitudinal Waves
Longitudinal Waves
Here are some example of longitudinal waves:
Pulling & pushing springs
Pulling & pushing springs
- Pushing the spring in and out (compressing and extending), longitudinal waves are created.
- The coils and the wave move along the same line.
Sound waves
Sound waves
- Sound waves are longitudinal waves.
P-waves
P-waves
- P-waves are pressure waves created during earthquakes.
- They are longitudinal waves.
- The P stands for primary.
