Electromagnetic waves include things like light, infrared, ultraviolet, radio waves, microwaves, and ... WebUnlike Conduction and Convection, Thermal Radiation requires no medium to transfer heat. The heat that the Earth receives from the sun is through Radiation. This is because radiation occurs through electromagnetic waves, and they do not need a medium for transmission. Thermal Radiation has another interesting property.

WebHeat energy transferred through radiation is as familiar as the light of day; in fact, it is the light of day. The sun is a huge thermal reactor about 93 million miles away in space, and neither conduction nor convection can produce any of the energy that arrives to Earth through the vacuum of space.
