05 Question (4 points) When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. AE...

multiple choice
An electron in a certain atom could move from the ground state (E=E_O) 10 points to the first excited state (E=E_1) inside an infinite well by absorbing photon with wavelength 1. If while in this excited state a photon the wavelength N2 is sent to the electron to be absorbed, to which energy state will the electron move?
