Key Points
- Radiation is the method of heat transfer in which no medium is required.
- In radiation, heat is transferred through electromagnetic waves, which can travel through a vacuum or empty space.
- This means that radiation can occur between two objects that are not in contact with each other, and even between objects that are separated by a vacuum, such as the heat from the sun reaching the Earth.
- In contrast, the other two methods of heat transfer, conduction and convection, require a medium, such as a solid, liquid, or gas, to transfer heat.
- Conduction is the transfer of heat through a material or from one object to another in contact with it.
- Convection is the transfer of heat through the movement of fluids, such as liquids or gases.
