Uv Light Vs Blacklight

So in other words black light is uv light 450 100nm covering the 400 320nm spectrum.

Uv light vs blacklight. Strictly speaking a black light is a kind of uv light. Black light is nothing but uva light while uv light is basically composed out of uva uvb and uvc. Most of the light that a black light emits is in the uva category invisible to the human eye. There are a lot of everyday materials that fluoresce or glow when placed under a black light.

So occasional exposure to a blacklight blue bulb is not expected to cause any health problems. In colloquial english however the term black light is often applied to party or decorative lights while uv light refers to lights used for a different purpose. Black light and ultraviolet uv light are synonyms that refer to the same phenomenon. Black lights emit ultraviolet radiation uv light.

In the last few years germicidal uv light helped quit the spread of countless virus like the influenza as well as various other superbugs. For years researchers have actually understood about the sanitation capacity of ultraviolet wavelengths particularly germicidal uv also recognized as uv c. Black lights while we typically refer to blacklight blue bulbs as black lights now you know that s. Ultraviolet light encompasses a wide range of wavelengths but most blacklight applications utilize a narrow range of ultraviolet radiation uv a to produce fluorescence effects specifically between 350 and 400 nm nanometers.

Blacklight is a specific type of mostly uva light that looks dark purple at least the small amount of light that is in the visible spectrum wavelength. The reason for the light s violet and blue color. But even within the 350 400 nm range different wavelengths can create stronger or weaker fluorescence effects. 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.

A black light gives off highly energetic ultraviolet light. When the filament is lit the longer uv wavelengths bypass the glass and are not filtered by the dark colored dye. To better understand the difference it s essential to know what each of the terms means. The black light emitted by the deep purple bulbs and tubes is an invisible wavelength of light with uv qualities.

You can t see this part of the spectrum which is how black lights got their name.
