Thermal Radiation Worksheet
📚 What is Thermal Radiation?
Thermal radiation is the transfer of heat energy through electromagnetic waves. Unlike conduction and convection, thermal radiation can travel through empty space (vacuum) and does not require matter to transfer heat.
Examples of thermal radiation:
- Heat from the Sun reaching Earth
- Warmth felt from a fire
- Heat from an electric heater
- Infrared radiation from your body
Key facts: All objects emit thermal radiation. Hotter objects emit more radiation than cooler objects. Dark surfaces are better at absorbing and emitting thermal radiation than light surfaces.
