What is the frequency of ultraviolet light?

Just as visible light is composed of different wavelengths of light, ultraviolet light is divided into three different categories. UVA rays have wavelengths that are between 400 nanometers and 320 nanometers. Rays with wavelengths of 320 nanometers to 290 nanometers are UVB rays, and UVC rays have wavelengths between 290 and 10 nanometers. read more

Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. However, too much exposure to UV radiation is damaging to living tissue. read more

The frequency range of ultraviolet waves is between 7.5 x 10^14 and 3 x 10^16 Hertz. For this range, the corresponding ultraviolet light wavelengths are 400 to 10 nanometers. Ultraviolet light waves are below the visible light spectrum. read more

Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight constituting about 10% of the total light output of the Sun. read more
