what is thermal radiation?
Asked by prakamya | 04 Dec, 2009, 11:01: AM
answered-by-expert Expert Answer

Thermal radiation is electromagnetic radiation emitted from the surface of an object which is due to the object's temperature. An example of thermal radiation is the infrared radiation emitted by a common household electric heater. If the heater is dissipating more heat, then the wavelenght falls in the visible range, and the thermal radiation makes the heater glow.
