A wave is a disturbance or oscillation that travels through space and matter, transferring energy from one place to another without the transfer of matter. Waves can be classified based on how they move, like mechanical or electromagnetic waves.
For example:
- Mechanical waves (like sound waves or water waves) require a medium (like air, water, or solid substances) to travel through.
- Electromagnetic waves (like light, radio waves, and X-rays) can travel through a vacuum and don’t require a medium.
Waves have different properties, including:
- Amplitude: The height of the wave, related to its energy.
- Wavelength: The distance between two consecutive peaks or troughs of the wave.
- Frequency: The number of waves that pass a point in a certain amount of time.
In simple terms, waves are a way for energy to move from one place to another!
