The glow of the sun is an example of which type of heat transfer?

The glow of the sun exemplifies radiation as a type of heat transfer. This process occurs when energy is emitted in the form of electromagnetic waves, allowing heat to travel through space without the need for a medium. Unlike conduction, which requires direct contact between objects for heat exchange, or convection, which involves the movement of fluids to transfer heat, radiation allows heat from the sun to reach the Earth across the vacuum of space. This principle underlines why we can feel the warmth of sunlight even though there are vast distances involved, showcasing the unique capabilities of radiative heat transfer. Absorption is not a method of heat transfer itself, but rather describes the process by which a material takes in radiative energy.
