Here's a breakdown:
* Transverse wave: A wave where the particles of the medium oscillate perpendicular to the direction of wave propagation. Think of a ripple in a pond or a wave on a string.
* Direction of travel: The path the wave energy moves along.
* Perpendicular: At a right angle to.
Examples of transverse waves:
* Light waves: Electromagnetic waves that travel through a vacuum.
* Waves on a string: The string vibrates up and down, but the wave travels horizontally.
* Water waves: The water particles move in a circular motion, but the wave travels horizontally.
