    That really depends on the medium that the wave happends to be sailing through at the moment, because it depends on the wave’s speed in that medium.

    I’m going to assume that the wave is in vacuum right now, where its speed is 3 x 10⁸ meters per second. Having that number, I can go ahead and solve the problem that I just invented.

    Wavelength = (wave speed) / (frequency)

    Wavelength = (3 x 10⁸ m/s) / (5.0 x 10¹⁴ /s)

    Wavelength = 6 x 10⁻⁷ meters

    That’s like 600 nanometers . . . a wave of orange light.
