Question

do humans emit electro magnetic radiation? if so, what are some cool facts about it?

Answer 1

Yes, humans emit heat as infrared and radiation. while infrared radiation is invisible to human beings it is not invisible to cats and dogs and other animals that hunt at night..



"...36 Amazing Facts about Infrared Radiation

1. Almost half of the energy arriving to the Earth from the sun comes as infrared light.



2. Anything which has a temperature puts out heat or infrared light.



3. Infra Red waves are also given off by stars, galaxies, lamps, flames and anything else that’s warm – including you...



...4. One of the advantages of IR observation is that it can detect objects that are too cool to emit visible light. This has led to the discovery of previously unknown objects such as comets, asteroids and wispy interstellar dust clouds.



5. Everything has some heat and puts out infrared light. Even things that we think of as being very cold, like an ice cube – put out some heat.



6. Infrared light can travel through thick smoke, dust or fog, and even some materials.



7. In firefighting, infrared cameras are being used to locate people or animals in heavy spots and to detect hot spots in forest fires.



8. Humans, at normal body temperature, radiate most strongly in the infrared at a wavelength of about 10 microns. (A micron is the term commonly used in astronomy for a micrometer or one millionth of a meter.)...".

Answer 2

Humans would emit MAGNETIC energy as a result of electric energy running through nerves----as electricity running through a conductor creates a magnetic field around a conductor. HEAT is the result of molecules vibrating after being IMPINGED upon by a chemical reaction or IR radiation. which the body may emit.



There is not enough EMF energy produced by the brain to make anything like Telepathy possible using the "Radio transmitter/receiver analogy"---- which is a strike against THAT particular telepathy THEORY. Modern proponents of telepathy speculate it works via "Quantum Entanglement" instead, thus explaining it's unlimited range and apparent FTL speed.

Answer 3

This has nothing to do with astronomy and space. It has to do with physics, and perhaps biology. Please choose your category more carefully

Answer 4

All living creatures including the species known as H0mo sapien emit infra red light. That's what the cops use to find you when you have been out at night committing your customary felonies.



Cheers!

Answer 5

We do. All things that generate heat (like we do) emit EM radiation.

Answer 6

As your skin temperature is about 90F or 305K, the peak wavelength of the radiation you emit is given by Wien's Displacement Law:



lambda-max = b/T,

where b = 2900 micron*Kelvin. Hence, the peak wavelength is

(2900 micron*Kelvin)/(305 Kelvin) = about 9.5 microns.



For comparison, the typical thickness of a European human hair is 70 microns.

Answer 7

We sure do. Look at us with IR lenses and you'll see humans glowing. That's infrared EMR, otherwise known as heat radiation. So that's not cool at all.

Answer 8

Every object with a temperature above absolute zero emits EM radiation, in the IR band.
