Waves move in a transverse or longitudinal pattern. Here's a breakdown of each:

Transverse Waves:

* Movement: The particles in the medium (like water or a rope) move perpendicular to the direction the wave travels.

* Example: Imagine shaking a rope up and down. The wave travels along the rope, but the rope itself moves up and down (perpendicular to the wave direction).

* Other Examples: Light waves, electromagnetic waves

Longitudinal Waves:

* Movement: The particles in the medium move parallel to the direction the wave travels.

* Example: Imagine pushing a spring back and forth. The compression and expansion (the wave) travels along the spring, and the spring itself moves back and forth (parallel to the wave direction).

* Other Examples: Sound waves

Important Note:

* The wave itself does not move the medium forward. The medium oscillates around a fixed point.

* The energy of the wave is what travels through the medium.
