Ultraviolet radiation has a wavelength between 10 and 400 nanometers. The shorter the wavelength, the more energy each photon contains. To find the frequency, divide the speed of light (299,792,458 metets per second) by the wavelength.
Infrared and Ultraviolet light fall just outside human vision. The frequency of infrared light is less than the frequency of visible red light. There are different definitions and classifications of infrared, but the frequency ranges from 3 x 10 11 Hz (300 Gigahertz or 1000 micrometer wavelength) to about 4.3 x 10 14 Hz (0.7 micrometer wavelength). Ultraviolet's frequency is greater than the frequency of Violet light. This can range from 7.5 x 10 14 Hz (400 nanometer wavelength) to 3.0 x 10 16 Hz (10 nanometer wavelength). See related links.
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
3*10^8/(1.88*10^-8)=1.60 × 10^16 Hz
The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency.The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.
Frequencies in the range 30 PHz (PetaHertz) to 750 THz (TeraHertz), Wavelengths from 10 nm to 400 nm.
Radio waves and ultraviolet waves are the same physical phenomenon.The difference is that radio waves have a much greater wavelength.(That's equivalent to saying that they have a much lower frequency.)

For light they would be gamma rays, or waves with a frequency greater than 1 * 10^20 (10000000000000000000) Hz. And really, as a general rule, the higher the frequency the shorter the wavelength. If you want to calculate the frequency or wavelength you take the speed of light (~3.00*10^8 m/s) and divide it by either the frequency or wavelength, and your answer will be the wavelength (if you used frequency) or the frequency (if you used wavelength).
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.
