What is Germicidal Ultraviolet Light?

  • The following diagrams tell you

    • Ultraviolet light, or UV, is a part of the electromagnetic spectrum with a wavelength ranging from 100 to 400 nanometers.
    • Thus, it is shorter than visible light but longer than X-Rays, as shown below.

    • Ultraviolet is further classified into 3 wavelength ranges:
    • UV-C, from 100 nanometers (nm) to 280 nm (Referred to as Germicidal Light)
    • UV-B, from 280 nm to 315 nm (Referred to as Sunlight)
    • UV-A, from 315 nm to 400 nm (Referred to as Blacklight)
