Convert 530 nanometers into meters:
530 / 10^9 =5.3 x 10^-7 meters
Frequency =Speed of light / Wavelength
F =3 x 10^8 / 5.3 x 10^-7
F =566,037,735,849,056.6 =5.66 x 10^14 Hertz.
Energy = Frequency x Planck's constant
E =[5.66 x 10^14] x [6.626 x 10^-34]
E =3.750316 x 10^-19 - Jules -energy of a photon of orange light.
