radiative heat transfer

Radiative heat transfer is the process of heat energy moving through electromagnetic waves, primarily infrared radiation, from a warmer object to a cooler one. Unlike conduction or convection, it doesn't require a medium like air or water; heat can travel through vacuum. For example, the sun warms the Earth through radiation. The amount of heat transferred depends on factors like the temperature difference, surface properties, and the nature of the materials involved. This process is essential in many natural and technological systems, including climate regulation, solar energy collection, and thermal insulation.
