    Wavelength of any wave = (speed) / (frequency)

    Speed of light = 300,000,000 m/sec

    Wavelength = 3 x 10 to the 8 / 750 x 10 to the 12 = 4 x 10 to the - 7 or 400 nanometers.

    Wavelength (L) is equal to the Speed of Light (c) divided by the Frequency (f); L = c / f

    L = (299,792,458 m/s) / (750E12 Hz) = 3.9972E-7 = 399.72E-9

    or roughly 400 nanometers
