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...

Consider the energy levels for Hydrogen in the table below: (note the energy is relative to the energy necessary for an electron to escape. So for Level n = 1 the electron would need to gain 13.6 electron volts to no longer be negative and thus able to escape the atom!) Level (n = ) Energy (in eV) 1 -13.6 2 -3.40 3 -1.51 4 -0.850 5 -.544 6 -.378 What would be the energy of a photon emitted when...
