Photon energy E =
Explanation:
A photon is quanta of light/or electromagnetic waves.
the wavelength of light is related with its frequency
and the energy of a photon is equal to h.f
therefore the
photon's Energy
h=Plank's Constant = 6.63. 10^-34 Js and
c = speed of light =3. 10^8 m/s
E= 19.89 . 10^-17 Joules
or in eV E =0.12 eV ( as i eV = 1.6. 10^-19 J )
