Here's a breakdown:
* Transverse Wave: A wave where the particles of the medium move perpendicular to the direction the wave is traveling.
* Disturbance: The change in the medium that is caused by the wave.
Examples:
* Water waves: The water particles move up and down (vertically) while the wave travels horizontally.
* Light waves: The electric and magnetic fields oscillate perpendicular to the direction of the light wave's travel.
* A wave on a string: When you shake a rope up and down, the wave travels horizontally along the rope, but the rope itself moves up and down.
Key takeaway: The disturbance in a transverse wave is the movement of the medium particles in a direction *different* from the wave's propagation.
