(2.13) Selection rules in hydrogenHydrogen atoms are excited (by a pulse of laserlight that drives a multi-photon process) to a spe-cific configuration and the subsequent spontaneousemission is resolved using a spectrograph. Infra-red and visible spectral lines are detected only atthe wavelengths 4.05 um, 1.87 µm and 0.656 µm.Explain these observations and give the values ofn and l for the configurations involved in thesetransitions.

Given: Let us consider the hydrogen selection rules A spectrograph is used to resolve the…

1.2) In a region of gas where the optical depth is 2.0, what percentage of photons can escape without being scattered or absorbed?
For crystal diffraction experiments, wavelengths on the order of 0.25 nm are often appropriate. Find the energy in electron volts for a particle with this wavelength if the particle is (a) a photon; and (b) an electron.
In the classical limit calculate the wavelength corresponding to an electron with the energy of 99 kev (kiloelectronvolt). Give your answer in Angstrom (10-10 1.6x10-10 m, then write 1.6 as your answer). This m, for example, if the answer is should give you a good idea why one can use a crystal lattice with an average interatomic distance of around 1010 m to observe electron diffraction.
