    Answer:

    652.9 GHz

    Explanation:

    E (photon energy) = h (Planck constant) times c (speed of light in vacuum) divided by λ (photon’s wavelength)

    h and λ are constants so photon energy E changes in inverse relation to wavelength λ.

    Frequency = c (speed of light) divided by λ (wavelength) =

    299,792,458 m/s divided by (0.459203 x 1^-3 m) = 652.9^9 Hz

    Hope I typed this right. 😛
