Question

Is the wavelength of infrared light too long or short to be seen by humans?

Answer 1

Range of wavelength of Infrared ray is from 10 raise to power -6 to 10 raise to power -3 (m)

Visible light keeps running from about 0.7 (red) to 0.4 microns (purple), so anything longer than that is "infrared" which signifies "underneath red". It's a little fuzzier where infrared finishes and microwaves start. 100 microns is one conceivable definition. Earthbound radiation crests at around 10 microns, so that is certainly IR. 300 GHz is 1 mm or 1000 microns, and it's certainly microwaves. Terrahertz radiation is no-one can see land between microwaves and infrared, and 1 Terrahertz is 333 microns.  

The exposed human eye can't see infrared light, on the grounds that the stripped human eye just has a restricted range of lights/hues that it can see. Infrared light isn't in the visible range.  

The briefest wavelength is violet and the longest wavelength is red, and that the human eye can't see Infrared light since it just has a restricted range, yet innovation has enabling us to perceive what we call " Infrared Light" ,in cameras, Ipods, Ipads, Apps from the PC and other numerous ways you could.

Answer 2

Answer :- Too long .

Extra information :- Wavelength and frequency . Electromagnetic radiation is transmitted in waves or particles at various wavelengths and frequencies. This expansive scope of wavelengths is known as the electromagnetic range . Infrared waves are longer than those of noticeable light, just past the red end of the obvious range.
