EE2 Problem Set#1 Due 4/15/09 in class Question #1: (5 points) Calculate the de Broglie wavelength of a particle with mass equal to 1.5 gm and moving with a velocity of 10 miles per hour. (Watch your units!) Question #2: (5 points) What is the de Broglie wavelength of an electron that has a kinetic energy of 6 electronVolts (eV)? Question #3: (10 points) For a particle in a box that has width L and infinitely tall walls, what is the probability of finding a particle in L/4 < x < 3L/4.

Unformatted text preview: The integral you set up should be a function of n , , L , x . 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? Some information you may find useful 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...
