4. When a hydrogen atom is bombarded, the atom may be raised into a higher energy state. As the excited electron falls back to the lower energy levels, light is emitted. What are the three longest-wavelength spectral lines emitted by the hydrogen atom as it returns to the n = 1 state from higher energy states? Give your answers to three significant figures. The lowest possible state, n = 1, corresponds to the electron in its smallest possible orbit; it...

The energy levels of a particular quantum object are -11.8 eV, -5.5 eV, and -3.1 eV. If a collection of these objects is bombarded by an electron beam so that there are some objects in each excited state, what are the energies of the photons that will be emitted?

Electrons in an unknown atom(not hydrogen) are excited from the ground state to the n=3 energy level. As these electrons make quantum jumps back to the ground state, photons of three different energies are emitted. The most energetic photon has an associated wavelength of 62.2 nm and the least energetic photon has an associated wavelength of 207 nm. What is the associated wavelength of the other type pf photon? The answer is 3-1 (20 eV), 3-2 (6 eV) and 2-1...

A certain type of atom
(not hydrogen) has three energy levels numbered 1, 2, and
3, as shown in the upper illustration. There are three possible
transitions between these levels that lead to emission of a photon:
3 ® 1, 3 ® 2, and 2 ® 1.
The lower illustration shows the emission spectrum from a gas of
these atoms. There are three emission lines, A, B, and C.
