Detailed explanation-1: -Infrared radiation is what we like to describe as heat. We can’t see infrared waves, but we can feel them. Your body gives off heat, so it is an emitter of infrared radiation.
Detailed explanation-2: -Infrared rays are a type of electromagnetic waves which are emitted by hot bodies. Within the electromagnetic spectrum, infrared waves occur at frequencies above microwaves below the wavelength of visible red light, that this type of electromagnetic waves termed infrared.
Detailed explanation-3: -The infrared waves present in the light ray coming from the sun is responsible for the heat energy. Thus infrared waves are called as waves of heat energy.
Detailed explanation-4: -Infrared radiation (IR), or infrared light, is a type of radiant energy that’s invisible to human eyes but that we can feel as heat. All objects in the universe emit some level of IR radiation, but two of the most obvious sources are the sun and fire.
