Webb30 juni 2024 · Light has a certain amount of energy which is inversely proportional to its wavelength. Thus, shorter wavelengths of light carry more energy and longer wavelengths carry less energy. A specific amount of energy is needed to promote electrons in a substance to a higher energy state which we can detect as absorption. WebbUltraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum. UV "light" spans a range of wavelengths between about 10 and 400 nanometers. The wavelength of violet light is around 400 nanometers (or 4,000 Å). Ultraviolet radiation oscillates at rates between about 800 terahertz (THz or 10 12 hertz) and 30,000 THz.
