-- They can't be called radio waves or microwaves, because no radio receiver
designed by man can detect them.
-- They can't be called X-rays, because they don't fog X-ray film.
-- They can't be called visible light waves, because nobody can see them.
-- They can't be called gamma rays, because they're not emitted in nuclear decay.
-- They can't be called ultraviolet waves, because their frequency is lower than
the frequency of visible light.
-- In many 19th Century Physics laboratories where infrared waves were being
studied, it was observed that the presence of infrared waves was often correlated
with a warm sensation on the surface of the human body. After correcting for all
other possible causes, such as wet pants and female post-doc lab assistants, it
was concluded that the warmth arose from the waves themselves, and they were
dubbed "heat", in recognition of the reaction they were able to bring about.
Infra can mean "Sub" or "below."
Picture a rainbow, the region just below RED, that you cannot see, is Infrared--"below the red."
Likewise, Ultra means "super" or "above." Picture that same rainbow, the area above the purple/violet that you cannot see is Ultraviolet, "above the purple."
Not much, they are just the part of the electromagnetic spectrum between microwaves and visible light.
Infrared radiation is "radiant heat".
by heat
induce resonance in molecules and increase internal energy in a substance.
Infrared waves.
If there is one thing you should know, it's infrared waves. Obvi.
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.
Is called infrared.

by heat
The ones called "heat waves", or infrared radiation.
induce resonance in molecules and increase internal energy in a substance.
Infrared waves.
infrared radiation
It is called thermal energy. It can be transferred by conduction, convection, or by radiation of infrared waves.
Infrared waves warm you providing heat and visible waves enable you to see.
Infrared is heat energy and heat energy can seriously hurt because it can burn
If there is one thing you should know, it's infrared waves. Obvi.
The transfer of heat by electromagnetic radiation is called thermal radiation. It is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.
