What is the wavelength (in nm) of light with a frequency of 6.29 x 1014 Hz?

Update:

What is the wavelength (in nm) of light with a frequency of 6.29 x 1014 Hz?

Note that the speed of light, c, is 3.00 x 108 m/s and 1 m = 109 nm.

    Sol

    c = f.λ

    3.0 × 10⁸ = (6.29 × 10¹⁴) × λ

    λ = 4.77 × 10⁻⁷ m

    = 477 × 10⁻⁹ m

    = 477 nm

    Wavelength (λ) = 477 nm

    lambda = c/frequency

    = (3.00 x 10^8 m/s)/(6.29 x 10^14 s^(-1))

    = about 5 x 10^(-7) m, but use a calculator,

    and then change it to 500 nm (but put in three significant figs, not 1)
