    6.34 x 19^14 Hz

    Explanation:

    Wavelength, λ = 473 nm = 473 x 10^-9 m

    the relation between the frequency and the wavelength is given by

    v = f x λ

    where, v is the velocity of light in vacuum which is equal to 3 x 10^8 m/s.

    So, f = v / λ

    f = (3 x 10^8) / (473 x 10^-9)

    f = 6.34 x 19^14 Hz
