Speed of light dimensions of a capacitor, whereas the value of the vacuum permeability is fixed at exactly through the definition of the ampere. Rosa and Dorsey used this method in 1907 to find a value of . Another way to measure the speed of light is to independently measure the frequency "f" and wavelength "λ" of an electromagnetic wave in vacuum. The value of "c" can then be found by using the relation "c" = "fλ". One option is to measure the resonance frequency of a cavity resonator. If the dimensions of the resonance cavity are also known, these can be used
