Chem 124 Quiz #3 Peanut Butter Dr. Retsek Spring 2008 NAME: __ KEY ____________________ Computer #: ________ 1. (10 points) Consider only transitions involving the following six energy levels for the hydrogen atom as you answer the following question: a. Draw the arrow ( ) on the left diagram above depicting the transition that would absorb the photon with the shortest wavelength between adjacent levels . Absorb: low level to high level, shortest wavelength means largest energy (energy is proportional to 1/ λ ) b. Draw the arrow ( ) on the right diagram above depicting the transition that would emit the photon with the lowest frequency between adjacent levels . Emit: high level to low level, low frequency means smaller energy (energy is propotional to ν ) c. Calculate the frequency of the photon emitted in a hydrogen atom for the transition from n = 4 to n =1. Two ways to do this: Method 1: 1 15 34 18 photon photon atom 18 atom 2 2 18 atom s 10 3.1 ν s)( ν ) J 10 (6.626 hv J 2.04x10
