Thermal radiation is electromagnetic (electricity that has been magnetized) radiation emitted from the material due to the heat of the material, the characteristics of thermal radiation depend on its temperature increasing the thermal radiation will increase the heat. this energy is emitted in all directions and travels directly to its point of absorption at the speed of light. Thermal radiation does not require any medium so it moves in a vacuum.
.An example of thermal radiation is the infrared radiation emitted by a common household electric heater.
