The photon is absorbed, and then a second photon is emitted from the excited electron giving a net change in energy and momentum of the electron. According to classical wave theory the momentum of a wave is p = E/v, the energy divided by the velocity, which is E/c for a photon.

Now use the above expression to find the energy of the photon released when a free electron is captured to the 2nd level. Use the relationship between a photon’s energy and its wavelength to calculate the wavelength of the photon emitted in question 2. Compare the wavelength for this transition with the lab spectrum of hydrogen below.
