Johann Wilhelm Ritter.
Ultraviolet waves were discovered by the German physicist Johann Wilhelm Ritter in 1801 during his experiments with silver chloride. He found that invisible rays beyond the violet end of the spectrum had a photographic effect on silver chloride, leading to the discovery of ultraviolet light.
I think in the ultraviolet region of the electromagnetic spectrum.
Ultraviolet Light is part of the electromagnet spectrum, with a frequency of between 10 15 and 10 16 Hz. It has a typical wavelength of between 10 -7 and 10 -8m. UV light was discovered in 1801 by Johann Ritter
Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)

Actually, the part of the electromagnetic spectrum that we can see is called visible light, not ultraviolet light. Ultraviolet light is outside the visible spectrum and is not visible to the human eye.
White dwarfs have a broad spectrum, ranging from ultraviolet to near-infrared. However, they are most prominent in the blue and ultraviolet part of the spectrum, due to their high surface temperatures.
The ultraviolet spectrum stretches from about 10 nm to about 400 nm wavelength. In terms of the number of frequency doubles (think octave), this range is about 10.8 times the breadth of the visible light spectrum.
