Radiation is a form of heat transfer that occurs through electromagnetic waves, such as infrared radiation. Unlike conduction and convection, radiation does not require a physical medium, allowing heat to travel through the vacuum of space. This is how the Sun’s energy reaches Earth. Radiation is also involved in everyday processes, such as heat from a fire warming nearby objects or the Earth’s surface emitting heat at night.
