Calculate the Energy (E) in joules for that wavelength and record it in the table below. Remember that E = HF, where h the Planck constant (6.6 *10^-34 j*s)

In that formula for Energy, 'F' is the frequency of the photon. But Frequency = (speed)/(wavelength), so we can write theEnergy formula as                                 E = h c / (wavelength) .So the energy, in joules, of a photon with that wavelength, is . . .                                 E = (6.6 x 10⁻³⁴) x (3 x10⁸) / (that wavelength)                                    = (1.989 x 10⁻²⁵) / (that wavelength, in meters) .
