Unformatted text preview: The integral you set up should be a function of n , , L , x . We know the wave function for a particle in an infinite box is 2 L sin n x L and that the probability of finding a particle is 2 x 1 x 2 2 L sin n x L dx L 4 3 L 4 2 Question #4 (10 points) What is the change in energy (in electronVolts) when an electron moves from the n=2 level to the n=1 level of a Hydrogen atom? h 6.626 *10 34 J * s 1 eV 1 electronVolt 1 Volt * charge of one electron 1.6 *10 19 J 8.85 *10 12 F m F Farad Coulomb Volt e 1.6 *10 19 C C Coulomb Volt Joule Coulomb E 1 2 m e 2 4 h n 2 E ( n 2) E ( n 1) 10.19 eV...
