Question

Consider the following energy-level diagram for a particular electron in an atom.

Based on this diagram, which of the following statements is incorrect?
A) The wavelength of a photon emitted by the electron jumping from level 2 to level 1 is given by .
B) If the electron is in level 1, it may jump to level 2 by absorbing a photon with energy of E.
C) If the electron is in level 1, it may jump to level 2 by absorbing any photon having energy of at least E.
D) We would observe an electron jumping from level 2 to level 1 as a single line in a line spectrum.
E) If the electron is in level 2, it may jump to level 1 by emitting a photon with energy of |E|.
