Angstrom (Å), unit of length used chiefly in measuring wavelengths of light, equal to 10−10 metre, or 0.1 nanometer. In optics, the situation is different: In most cases, wavelength is used instead of frequency although this leads to a certain complication: For example, green light has a wavelength of 520 nm in vacuum, but in water its velocity is smaller by a factor of 1.33 and thus, in water the same green light has a wavelength of only 520 / 1.33 = 391.0 nm. micrometers, nanometers, and meters.
