(a) What energy (in eV) would a photon have, if it were emitted when an electron dropped from the n = 5 level to n = 2? 2.865 eV (b) The equation for a photon's energy can be written: Echo where h is known as Planck's constant and is equal to 4.136 x 10-15 eV · s. (Note that h has a different numerical value in SI units.) Since we know that for light © = f, we can rewrite...
