1. Consider the following energy levels of a hypothetical atom: E -1.0 x 10-19 -5.0 x 10-19 _-10 x 10-19 _-15 x 10-19 a. What is the wavelength of the photon needed to excite an electron from E, to Ex? (Use the Energies given in the problem) b. When an electron drops from the E3 to the E, level, the atom is said to undergo emission. Calculate the wavelength of the photon emitted in this process.
Let Ho be the Hamiltonian of the non-relativistic hydrogen atom neglecting spin. Consider H1 = e|E\r cos 0 with e|E|af < 1. This Hamiltonian describes a weak constant electric field in the z-direction interacting with the atomic dipole. We want to understand the effect such a field has on the first excited energy level, E2, of hydrogen. Remember that this energy level is degenerate with corresponding eigenstates |2lm) Use first-order perturbation theory to find the aproximate energies of Ho+ H1...
The quantum-mechanical treatment of the H atom gives the energy, E, of the electron as a function of n: where h is Planck's constant, me is the electron mass, and a0, called the Bohr radius, is 52.92×10−12 m. Calculate the wavelength in nm of the photon emitted in the jump between n = 1 and n = 4.
Below is both an energy level diagram for an atom and an emission spectrum for that atom. Match the peak in the emission spectrum to the corresponding transition in the energy level diagram.

Interactive LearningWare 30.1 reviews the concepts that play roles in this problem. A hydrogen atom emits a photon that has momentum 6.460 × 10-27 kg·m/s. This photon is emitted because the electron in the atom falls from a higher energy level into the n = 1 level. What is the quantum number of the level from which the electron falls? Use values of h = 6.626 × 10-34 J·s, c = 2.998 × 108 m/s, and e = 1.602 ×...
