Ultra violet light is not visible!
Lower
Compared to the visible light ultra violet has shorter wavelength
Ultraviolet has a shorter wavelength than red, green, or infrared light.
The ultraviolet spectrum is 'beyond' (ultra) the violet part of the visible spectrum, that is, beyond the short end of the wavelength range. The infrared spectrum is 'within' (infra) the long end of the wavelength range. The two terms have nothing to do with color, which defines the visible spectrum between violet and red.
"UV" (ultra-violet) is radiation with shorter wavelength/higher frequency than visible. Infrared is radiation with longer wavelength/lower frequency than visible.
Yes, it does. UV-C wavelength is 200-280 nanometers, UV-B is 280-320 nm, and UV-A is 320-400nm.
You can see visible light but not ultra violet light.
Ultra violet
They may emit some energy in that wavelength, but most of their output is in the ordinary visible band.
An ultra violet (UV) ray is an electromagnetic wave, it is the same kind as visible light wave just with a different wavelength and frequency. Both travel and the speed of light. It is a transverse wave
one of them is violet and ultra violet
Ultra violet radiation has a shorter wavelength than visible light; this is true regardless of whether it is a star or any other source that is emitting it.
