Here's why:

* Transverse Waves: In transverse waves, the particles of the medium oscillate or move *perpendicular* to the direction the wave itself is traveling. Imagine a rope tied to a wall. If you shake the rope up and down, the wave will travel horizontally along the rope, but the individual particles of the rope will move vertically.

* Examples of Transverse Waves:

* Light waves

* Electromagnetic waves

* Waves on a string

* Water waves (to some extent - the water molecules move in a circular motion, but there's a vertical component)
