    6.45 x 10-7 meters

    Explanation:

    Taking speed of light as 300000000 m/s

    We know that speed of light is product of wavelength and frequency and expressed as

    s=fw

    Where s represent speed, f is frequency and w is wavelength

    Substituting 4.65*10^14 Hz for frequency then the wavelngth will be given by

    300000000=4.65*10^14 * w

    w=300000000:4.65*10^14

    w=6.451612903225*10^-7 m

    Rounded off, the wavelength is 6.45 x 10-7 meters
