Infrared (electromagnetic wave with wavelength between microwave and visible light), this entry is reviewed by the compilation and application project of “popular science China” Science Encyclopedia.
Infrared is an electromagnetic wave whose wavelength is between microwave and visible light. The wavelength is between 1mm and 760 nm, which is longer than red light.
Substances above absolute zero (- 273.15 ℃) can produce infrared. Modern physics calls it thermal ray. Medical infrared can be divided into two categories: near infrared and far infrared. Containing heat, the heat of the sun is mainly transmitted to the earth through infrared.
We call the radiation beyond the red light infrared (ultraviolet beyond the purple light), invisible to the naked eye.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at firstname.lastname@example.org in time and we will delete it at the first time.
