Frequency and wavelength are inversely proportional, as shown below in the rearrangements of equation 1a c = λ ν = 3.0 × 10 8 : ( 1b ) c λ = ν ( 1c ) c ν = λ A third variable in the wave is the amplitude, the intensity of the radiation; for visible light, this is perceived as brightness. Therefore, if we look at a given shade of blue, it will always have the same frequency and wavelength, but can be of different amplitudes. Another descriptor for radiation is chromaticity. Light can be monochromatic (a single wavelength) or polychromatic (many wavelengths such as white light). Light can also be
