Transverse Waves
* Definition: Waves where the displacement of the medium (or field) is perpendicular to the direction the wave travels. Imagine shaking a rope up and down – the rope moves vertically, but the wave travels horizontally.
* Examples:
* Light waves (electromagnetic waves)
* Waves on a string
* Ripples on the surface of water
Waves That Are NOT Transverse
* Longitudinal Waves: The displacement of the medium is parallel to the direction the wave travels. Think of a slinky being pushed and pulled – the slinky compresses and expands along the same direction the wave travels.
* Examples:
* Sound waves: Sound travels through air, water, or solids by compressing and expanding the medium.
* Seismic P-waves (primary waves): These are the fastest seismic waves and travel through the Earth by compressing and expanding the rock.
Key Takeaway
The key difference lies in the direction of the disturbance (displacement) relative to the direction the wave travels. Transverse waves have a perpendicular relationship, while longitudinal waves have a parallel relationship.
