What Are Examples of Infrared Waves?

Some examples of radiating infrared waves are burning charcoal, heat from an electric heater, fire or a radiator emitting warmth. Infrared radiation is a type of electromagnetic radiation that objects emit when they are hot but not quite hot enough to emit visible light. Because infrared radiation can be felt in the form of heat, it is also called thermal radiation.

A hotter object emits more infrared radiation. In the electromagnetic spectrum, infrared waves are found between the visible light and the microwave sections. Infrared waves have longer wavelengths than visible light.

Many objects and organisms give off infrared radiation. For example, since humans have a body temperature, they give off infrared radiation at a wavelength of about 10 microns. Infrared waves are used in many applications, including infrared telescopes and remote controls.
