Waves are like messages sent across the sea. Imagine you're on a boat in the middle of the ocean, when someone throws a stone into the water nearby, it sends out ripples that reach your boat. Waves work in the same way: energy from the wind creates them, and they travel far across the ocean without needing the same wind to follow all the way.
Examples
- A pebble dropped into a pond sends out ripples that spread across the water like tiny waves.
- If you push on a swing, it keeps going back and forth even after your push stops.
