Human body temperature is about 98.6 degrees. at what wavelength do humans radiate the most energy?

Question

what kind of radiation do we emit???

Answer 1

It's long infrared.  The Celsius temperature is 37, which in Kelvin is 310, and you can use Boltzmann's constant (1.38E-23 joules/Kelvin), Planck's constant (6.626E-34 joule-seconds), and the speed of light (3E8 meters/second) to work out the exact number.

Answer 2

we radiate at a wavelength between 750nm and 1mm.

The kind of radiation that humans emit is infrared radiation

found this note in the slide:

Since our body temperature is about 98.6 as you said, anything that has a temperature above absolute zero emits photons(light). You can only see other people when there is light to reflect off of them.  We do not glow in the dark in visible light, only in the IR!
