2015 AP Physics 2 - Modern Physics Modern Physics Question 3 The electron energy levels for a mercury atom are shown below. E =0 Ex - - 4.95 eV E3 - -5.52 ev E2 = -5.74 eV E1 = - 10.38 eV A. An electron in the ground state absorbs a photon which causes the electron to be raised to the second energy level. Determine the following for the absorbed photon. i. wavelength ii. frequency B. State whether or not the absorbed photon is in the visible range. Explain your answer . C. The electron absorbs a second photon of energy 10.00 eV while it is in the second energy level of the atom. Find the kinetic energy for the electron after it absorbs the 10.00 eV photon. Copyright @ 2013 National Math + Science Initiative , Inc., Dallas, TX. All rights reserved
