In addition, infrared ray (infrared) is electromagnetic wave between microwave and visible ray for the wavelength, wavelength is at 760 nanometers
Between (nm) to 1 millimeter (mm), the long non-visible light than ruddiness.Can produce higher than the material of absolute zero (- 273.15 DEG C)
Raw infrared ray.Modern physics is referred to as heat ray.Medical infrared ray can be divided into two classes: near infrared ray and far infrared.Containing heat
Can, the heat of the sun mainly passes to the earth by infrared ray.
Infrared ray is one of numerous invisible rays in sunray, is sent out in 1800 by British scientist He Xieer
Existing, it is also called infrared emanation, sunshine prism is disassembled by he, the ribbon position of various different colours placed
Thermometer is it is intended to measure the heating effect of the light of shades of colour.It was found that thermometer being located at outside ruddiness heats up
Hurry up.Therefore it is concluded that in solar spectrum, the outside of ruddiness there will necessarily be invisible light, here it is infrared ray.Can also
Medium as transmission.On solar spectrum, ultrared wavelength is more than luminous ray, and wavelength is 0.75～1000 μm.Infrared ray can
It is divided into three parts, i.e. near infrared ray, between wavelength is (0.75-1)～(2.5-3) μm；Middle infrared (Mid-IR), wavelength be (2.5-3)～
(25-40) between μm；Far infrared, wavelength is between (25-40)～l500 μm.
