Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on Earth possible. Heat travels from the sun by a process called radiation. Radiation is the transfer of heat by electromagnetic waves.
In particular, the heat lamp you have in your bathroom. The heat lamp beams out heat to you and keeps you warm through radiation. Radiation is light that can transfer heat. Heat 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 would produce any of the energy that arrives to Earth through the vacuum of space. The sunâs energy gets to the Earth through radiation, which you can confirm on a sunny day just by standing outside and letting the sunâs rays warm your face.
