black light
 
NOUN:
Invisible ultraviolet or infrared radiation. Black light causes fluorescent materials to emit visible light and is used to take pictures in the dark.
 

Who invented the black light?

 
William H. Byler is credited with inventing the black light in 1935, and according to the University of Central Missouri, Byler graduated there in 1927 with a major in chemistry and physics.

How Black Light Works

A black light works by producing UVA light, or ultraviolet light, that we cannot see. Ultraviolet light is above the spectrum of visible light that our eyes can process. When objects appear to glow under the light, they are substances that are emitting light in response to radiation. These "phosphors" are what make normal things like teeth and white t-shirts glow in the dark! See our black light uses section.

 

Black Light Term

The term black light refers to a specific kind of lamp---typically fluorescent---with a special phosphorescent coating that emits UV radiation in the UVA range.
Black lights are a kind of fluorescent light with a special coating of phosphor, functioning as a ubiquitous accessories in college dorm rooms. Phosphors fluoresce (give off light) when hit by radiation. The black glass in a black light blocks normal visible light so the only light hitting the phosphor coating is in the ultraviolet spectrum. Ultraviolet light is electromagnetic radiation just like visible light but it is slightly more energetic. Undetectable by the human eye, when UV light hits certain materials, called phosphors, it causes them to glow. Phosphors change the energy from the UV radiation to light we can see (visible light).

Types Of UV Light

Ultraviolet radiation (ultra meaning "beyond") encompasses its own range of light rays, all of which are undetectable by the naked eye (of humans, at any rate).

UVA rays are the longest-wavelength, lowest-energy kind of UV radiation and the kind that is least harmful. It is the UVB and UVC rays in sunlight that cause the most damage, prolonged exposure to which can lead to sunburn and skin cancer.

Black light is a kind of UV light. Black lights emit ultraviolet radiation (UV light). UV is radiation with a wavelength just shorter than that of violet light, which is the shortest wavelength of light in the visible part of the electromagnetic spectrum. The electromagnetic spectrum is the range of radiation from benign radio waves to highly dangerous gamma radiation.
Black light sources may be specially designed fluorescent lamps, mercury vapor lamps, light-emitting diodes, or incandescent lamps.

UV-A

UV-A light is often referred to colloquially as black light. This is the most visible type of UV light, because it has the longest wavelength. You can buy UV-A black light bulbs at most stores. They release bluish-purple light and are used in concerts and entertainment because certain colors appear to glow beneath them.

UV-B

UV-B and UV-C lights are more often referred to as UV lights than black lights. UV-B lights are medium-wavelength lights that release less visible light than UV-A lights do. UV-B lights are used in forensics, because certain human fluids are revealed under the lights. Police can use these lights, for instance, to find blood or fluids at a crime scene.

UV-C

UV-C lights have the shortest wavelength of all UV lights and are effectively invisible to humans. UV-C lights emit destructive radiation that kills germs. UV-C lights, therefore, are mostly used for sterilization and water purification purposes.

Black Light Applications

UV light also has other practical applications and artificial sources. A fluorescent lamp without the phosphorescent coating emits UV light in the UVC range--invisible and highly energetic. This light can cause damage to the skin with prolonged exposure but is commonly used as a disinfectant.

UV light is increasingly utilized in industrial and commercial applications. UV light-emitting diodes, or LEDs, are put to work in digital printing, where the light is used to cure printed materials. LEDs are used in traffic lights, indicator lights on airplanes and large stadium displays, due to their low energy consumption and small size.
