What is the energy of the electron in the ground state?
What is the energy of the electron in the first excited
state?
If the electron makes the transition shown by the red
arrow, from B to C, will a photon be absorbed or
emitted?
Calculate the wavelength of the photon that would be
absorbed or emitted. Round your answer to 3
significant digits.
