Study Notes
Light and Electromagnetic Radiation
- Light is a form of electromagnetic radiation.
- Electromagnetic radiation is a type of wave.
- Waves are a way energy is transferred through a medium.
Mediums
- A medium is the substance or material through which a wave travels.
- Examples include air, water, solids, and vacuum.
- The properties of the medium influence the wave's behavior.
- The speed of sound varies significantly depending on the medium (e.g., air to water).
- Different wave types (e.g., sound, light, electromagnetic waves) interact with different mediums in different ways.
