Ultraviolet: History & Applications

Ultraviolet radiation (UV; sometimes called ultraviolet light) is electromagnetic radiation of wavelengths of 100–400 nanometers, shorter than that of visible light, but longer than X-rays. Wavelengths between 10 and 100 nanometers are called extreme ultraviolet and share some properties with soft X-rays. UV radiation is present in sunlight and…
