Simply so, Is blacklight a UV light? Black lights emit a type of ultraviolet radiation called UVA, which is invisible to the human eye. They are often used in industry, nightclubs or amusement parks to make things glow. This glow is the energy emitted by the light being converted into visible light by particles called phosphors.
What glows green under UV light? Fluorite glows under UV light. The fluorescence phenomenon is named after fluorite, where it was first observed by George Gabriel Stokes in 1852. Fluorite can glow in a variety of colors, but most often, it occurs in vibrant blue or green color under UV light.

Do LED lights emit UV? Some in the lighting business have stated that LEDs do not produce UV radiation. However studies have shown that standard LEDs do create a small amount of UV. That said, the amount of UV they actually emit is even less. This is due to the phosphors within an LED lamp that convert the Ultraviolet light to white light.
Why is UV light purple?
UV light has a shorter wavelength than visible light. Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of « purpler-than-purple » light or « beyond violet » light.
