The energy of a photon is
E = h c / λ
where h is Planck's Constant ( 4.14 x 10-15 eV-s), c the speed of light ( 3.00 x 10^8 m/s), and λ the wavelength in meters. The answer will be in electron-Volts (eV).

velocity = frequency * wavelength 3*10^8 m.s-1 = frequency * 570 * 10^-9 m 3*10^8m.s-1 / 570*10^-9 m = frequency = 5.26 *10^14 Hz

Using Planck's Constant h = 4.136 x 10^-15 e-Volt Sec
and the equation E = h f where f is frequency
You can crank out the answer (remember to convert your wavelength to frequency)

Nothing. Wavelength is length and eV is energy. They are two different physical quantities.
