Transverse Waves:

* Particles move perpendicular to the direction of wave propagation.

* Imagine a rope tied to a wall. If you shake the free end up and down, a wave travels along the rope. The rope particles move up and down, while the wave itself travels horizontally.

* Examples: Light waves, electromagnetic waves, waves on a string.

Longitudinal Waves:

* Particles move parallel to the direction of wave propagation.

* Imagine a spring. If you compress a section of the spring and then release it, a wave travels along the spring. The spring particles move back and forth, compressing and expanding, in the same direction as the wave travels.

* Examples: Sound waves, seismic waves (P-waves).

Important Note:

* Particles do not travel with the wave. They oscillate or vibrate around their equilibrium position.

* The energy of the wave is what travels, not the particles themselves.

* The amplitude of the wave determines the maximum displacement of the particles from their equilibrium position.
