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. :P
