Transverse
In a transverse wave, particle vibration is perpendicular to the direction of wave travel.
Choose Your Level
Transverse
The wave travels one way, but particles move across that direction.
Recommended for Class 10
Transverse
In a transverse wave, particles of the medium vibrate perpendicular to the direction in which the wave travels.
For example, if a wave travels horizontally along a rope, the rope may move vertically up and down.
Crest and Trough
The highest point is called a crest.
The lowest point is called a trough.
Examples
waves on a stretched rope; electromagnetic waves; * S seismic waves.
Transverse — Advanced
Transverse waves involve displacement normal to the propagation direction. They can exhibit polarisation, a property that distinguishes them from ordinary longitudinal mechanical waves.
Common Mistakes
Common Mistakes
- Mistake
The particles do not travel with the wave.
- Mistake
“Transverse” describes the direction of vibration relative to propagation.
