Ionizing radiation enters a Geiger tube with 1.45 MeV of energy. As the radiation passes through the tube, all of this energy goes into creating ion pairs and each ion pair requires 30 eV of energy. (a) If an applied voltage sweeps these ions out of the gas in 1.30 µs, determine the current (in A). (b) Since the applied voltage in the Geiger tube accelerates these separated ions, creating other ion pairs in subsequent collisions, the actual current is...

The hydrogen atomic emission spectrum includes a UV line with a wavelength of 92.323 nm. Photons of this wavelength are emitted when the electron transitions to n_t = 1 as the final energy state. Is this line associated with a transition between different excited states or between an excited state and the ground state? different excited states between an excited state and the ground state What is the energy of the emitted photon with wavelength 92.323 nm?

Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in...
Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in the atom, just as it can only emit these discrete energies. When a spectrum is taken of the solar corona, in which a broad range of EM wavelengths are passed through very hot hydrogen gas, the absorption spectrum shows all the features of the emission spectrum. But when such EM radiation passes through room-temperature hydrogen gas, only the Lyman series is absorbed. Explain the...
