RadiationRadiation is the continual emission of infra-red (IR) waves from the surface of all bodies, transmitted without the medium.
All objects and surfaces absorb or emit radiant heat or IR radiation. The hotter the object, the greater the amount of radiant heat emitted. Factors that affected the rate at which radiant heat is emitted are
Shiny surfaces are also good reflector of IR radiation.
