answered-by-expert Expert Answer
Infrared Radiations are electromagnetic waves of wavelength in the range of 8000 to 107 .
These radiations lie just beyond the red end of visible spectrum. These are invisible radiations but can be sensed as heat.  All heated bodies such as a heated oven, flame, fire etc are the sources of infrared radiations. The Sun is the natural source of infrared radiations.
