Webwhere λ is the wavelength in vacuum and n is the medium’s index of refraction. It follows that the wavelength of light is smaller in any medium than it is in vacuum. In water, for example, which has n = 1.333, the range of visible wavelengths is (380 nm)/1.333 to (760 nm)/1.333, or λ n = 285–570 nm. WebWavelengths of electromagnetic radiation, whatever medium they are traveling through, are usually quoted in terms of the vacuum wavelength, although this is not always explicitly stated. Generally, electromagnetic radiation is classified by wavelength into radio wave, microwave, infrared, visible light, ultraviolet, X-rays and gamma rays.

Frequency is the number of waves that pass … WebUltraviolet radiation lies between wavelengths of about 400 nanometres (1 nanometre [nm] is 10 9 metre) on the visible-light side and about 10 nm on the X-ray side, though some authorities extend the short-wavelength limit to 4 nm. The application of sunscreen to the skin can help to block absorption of ultraviolet radiation in such persons. dlsu bachelor of science in commerce
