Typical Light Source Spectrum
The typical light source spectrum wavelength ranges from Ultraviolet Light (UVC 200-280nm, UVB: 280-315nm, UVA 315-400nm) to Visible Light (400-760nm) and Infrared Light (760-3000nm).
The image above shows the range of wavelengths; from Ultraviolet (UV) radiation, to visible light, to infrared radiation (IR)
Visible Light Wavelength and Perceived Color
| Wavelength Range (nanometers) | Perceived Color |
| 340-400 | Near Ultraviolet (UV; Invisible) |
| 400-430 | Violet |
| 430-500 | Blue |
| 500-560 | Green |
| 560-620 | Yellow to Orange |
| 620-700 | Orange to Red |
| Over 700 | Near Infrared (IR; Invisible) |
- The wavelengths range from less than 290 nanometers for UV-C (a very short, high-energy wavelength) to 3000 nanometers (a very long, low-energy wavelength)
- What's a nanometer? It is one-billionth of a meter - really tiny
