The Figure Shows the Energy Levels for an Electron in a Finite

question 21

Multiple Choice

The figure shows the energy levels for an electron in a finite potential energy well. If an electron in the n = 2 state absorbs a photon of wavelength 2.0 nm, what happens to the electron?

• A) It makes a transition to the n = 3 state.
• B) It makes a transition to the n = 4 state.
• C) It escapes the well with a kinetic energy of 280 eV.
• D) It escapes the well with a kinetic energy of 730 eV.
• E) Nothing; this photon does not have an energy corresponding to an allowed transition so it is not absorbed.
