A free electron with negligible kinetic energy is captured by a stationary proton to form an excited state of the hydrogen atom During this process a photon of energy E4 is emitted, followed shortly by another photon of energy 10 2 electron volts. No further photons are emitted. The ionization energy of hydrogen is 13 6 electron volts Determine the wavelength of the 10 2-eV photon Determine the following for the first photon emitted The energy E4 of the photon The frequency that corresponds to tins energy The following diagram shows some of the energy levels of the hydrogen atom, including those that are involved in the processes described above. Draw arrows on the diagram showing only the transitions involved in these processes. The atom is in its ground state when a 15-eV photon interacts with it. All the photon's energy is transferred to the electron, freeing it from the atom. Determine the following. The kinetic energy of the ejected electron. The de Broglie wavelength of the electron.
