E = hv
   = 6.626 x 10-34 x 50 hz
   = 331.3 x 10-34 J
   = 331.3 x 10-37 kJ
Energy of 1 photon = 331.3 x 10-37 kJ
Energy of 1 mole of photon = 331.3 x 10-37 kJ x 6.023 x 1023
                                        = 1995.042 x 10-14
                                        = 1.995 x 10-11 KJ/mole
Energy of 1 mole of photon radiation = 1.995 x 10-11 KJ
