What is the difference between the frequency of infrared and visible light?
What is the difference between the frequency of infrared(ir led strip) and visible light?Us to take exactly wavelength and explain all this. there are ir led 940nm & visible light 770~622nm.
Different wavelength of the electromagnetic wave. reflected in consciousness through sense organs is different by human.
770 ~ 622nm, the feeling is red;
622 ~ 597nm, orange;
597 ~ 577nm, yellow;
577 ~ 492nm, green;
492 ~ 455nm, indigo color;
455 ~ 350nm, purple
to infrared electromagnetic wave be anywhere from microwave and visible light,They are wavelength 760 nm to 1 mm,
Simply words: infrared wavelengths is long than the wavelength of visible light,visible light in the wavelength range about 360-800nm, and infrared wavelength range is wider than visible light, from about 900nm to tens of microns,belong to infrared. Of course,wavelength ever more long, frequency ever more lower!
