WebFrequency divided by the speed of light is ν/ c, which from the above equation is 1/λ. When wavelength is measured in metres, 1/λ represents the number of waves of the wave train to be found in a length of one metre or, if measured in centimetres, the number in one centimetre. This number is called the wavenumber of the spectrum line. WebMain article: Superluminal motion.
