It's units of measurement are typically given in measurements of length or metric units. How are different wavelengths of light seen? 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. UV-C is often used in hospital germicidal lamps. The SI unit is meter. Although the units for wavelength are units of distance, a wavelength still gives you information related to the time properties of a wave. It is named for the 19th-century Swedish physicist Anders Jonas Ångström. What is the consistency of lava in the composite volcanoes? How many Michelin stars does Gordon Ramsay have?
