What is the frequency of green light, which has a wavelength of 4.90 x 10 (to the power of -7) m?

Can everyone show work and explain how you find the frequency if all they give you is wavelength and nothing else.

    c = ν λ ν= frequency (Hz) and ~10^15 s^-1 green light,
    λ = wavelength in m,
    c = speed of light = 2.998 x 10^8 m s-1 that you are meant to look up in your text (back page)
