Waves
| Term | Definition |
|---|---|
| Wave | Any disturbance that transfers energy from place to place |
| Matter | Moves through mechanical waves |
| Medium | The matter a wave travels through |
| Sound waves | A type of mechanical wave It can travel through a solid, liquid, or a gas. They cannot travel through a vacuum |
| Electromagnetic wave | Transfers electromagnetic radiation |
| Energy | The ability to do work or cause change |
| Energy 2 | Transformed from one form to another and can be transferred from one object to another |
| Electromagnetic waves | It can travel without a medium Visible light , radio waves, X- rays, and microwaves |
| Mechanical wave | Begins when an energy source causes a medium to vibrate. They cannot travel direction of the vibration determines what type of mechanical wave is produced |
| Transverse wave | Travels perpendicular to the direction of the source’s motion. |
| Trough | The lowest point of a wave |
| Rest position | The amplitude of a wave is the maximum distance a wave travels |
| Longitudinal waves | Travel in the same direction of the vibration |
| Spring toy | Example of longitudinal waves |
| Rarefactions | Gaps between compressions |
| Surface waves | Combination of both transverse and longitudinal waves |
