Electromagnetic Radiation: Infrared Far infrared waves are thermal. In other words, we experience this type of infrared radiation every day in the form of heat! Shorter, near infrared waves are not hot at all - in fact you cannot even feel them. These shorter wavelengths are the ones used by your TV's remote control.
