Heat sources.
(or more generally, sources of electromagnetic radiation)
It is so far undenied (and "functions") that infrared is an electromagnetic radiation with a slightly higher wavelength = slightly lower frequency than visible light.
(search key words: infrared, frequency, wavelength, source)
Infrared propagates in vacuum as well as in the atmosphere.
Infrared penetrates slightly deeper into material than visible light (cf. "light therapy effects") or ultraviolet (which deposits its energy at the surface, causing for example a sun tan or skin cancer) and feels "warm".

How are infrared waves and infrared radiation related?
infrared waves and infrared radiation both are same
How does the human brain perceive infrared sound wave reflections from stationary metal objects?
The term "infrared" refers to electromagnetic waves, not to sound waves.
Are infrared waves are an example for longitudinal wave?
No, infrared is a type of electromagnetic waves, and those are transverse waves.
Are infrared waves longitudinal?
No. Infrared is a type of electromagnetic waves, and therefore, a transverse wave.
Where does infrared heat come from?
Infrared lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves that are near to visible light do not generate heat and are used in TV remote controls. Infrared waves that are far from the visible end of the light spectrum are thermal and generate heat. The infrared heat from the sun, a lamp or a radiator is a type of far infrared radiation.

What waves are used in an Iris scanner?
Infrared waves. Infrared waves are also used in retina scans.

Which waves are transmitted by a television remote control device?
They most use infa red but they use wireless for the more recent technology.
Are infrared waves sound waves?
No; sound is a mechanical wave, infrared is a part of the electromagnetic spectrum.
Higher frequencies ultraviolet waves or infrared waves?
Ultraviolet is higher frequency, then visible light, then infrared.
Does UV rays have longer wavelength than infrared?
UV waves are shorter than infrared waves.
What is infrared absorption?
This phenomenon is the absorption of infrared waves in a material.
Difference between infrared waves and red light waves?
Infrared waves have longer wavelengths compared to red light waves. The wavelengths of infrared waves are too long for the naked eye to see, while red light waves can be seen as part of visible light.
