6. Find the photon energy for the three longest wavelengths of the Balmer series and calculate the wavelengths.
7. The wavelength of the yellow spectral line of sodium is 590nm. At what kinetic energy would an electron have the same de Broglie wavelength?
8. If an excited state of an atom is known to have a lifetime of 10-7
seconds, what is the statistical spread in the energy of photons emitted
by such atoms in the spontaneous decay to the ground state?
