30.5 Applications of Atomic Excitations and De-Excitations 30. Figure 30.39 shows the energy-level diagram for neon.  a  Verify that the energy of the photon emitted when neon goes from its metastable state to the one immediately below is equal to 1.96 eV.  b  Show that the wavelength of this radiation is 633 nm.  c  What wavelength is emitted when the neon makes a direct transition to its ground state? 31. A helium-neon laser is pumped by electric discharge. What wavelength electromagnetic radiation would be needed to pump it? See Figure 30.39 for energy-level information. Ruby lasers have chromium atoms doped in an aluminum oxide crystal. The energy level diagram for chromium in a ruby is shown in Figure 30.64. What wavelength is emitted by a ruby laser?.
