Unformatted text preview: Quiz 9b Name: Date: Phys224 Spring 2010 Dr. P. Hanlet Concept (3 points each) 1. Which particle(s) will be quantized? (a) a proton in a 1D box (b) electron ionized from its atom (c) electron attached to the end of an infinitessimally small spring (d) all of the previous (e) (a) and (c) 2. An electron is excited to the n =4 state. When it spontaneously decays to the ground ( n =1) state, how many different possible energies of photons might be emitted? (a) 6 (b) 7 (c) 5 (d) 3 (e) 1 1 Problem (5 pts) Show your work!!! If I can read it, I will give you partial credit!!! Correct answers without work will NOT get full credit. 3. Suppose that an electron is in its ground state ( n =1) in an infinite square well of length L =200 pm . A photon of wavelength λ γ =16 . 5 nm excites the electron. (a) To which energy level will the electron be excited? (Show your work). Draw the transition on the energy level diagram....
