Physics for Electrical Engineers Prof. B. Jalali EE 2 Homework #1 Due: Jan 21, 2010 Please turn in your homework in class. 1. 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. (h=6.626 × 10 -34 J-s) 2. What is the de Broglie wavelength of an electron that has a kinetic energy of 6 electron-Volts? (1eV 1Volt × the electric charge on one electron.)

Unformatted text preview: 3. (a) Consider an electron in a potential box of dimension 1nm × 1.3nm × 1.5nm. Given that the mass of the electron is 9.1 × 10-31 kg, determine the components of momentum and the total kinetic energy of the state with quantum numbers (1, 2, 1) for (n x , n y , n z ) respectively. (b) Repeat part (a) for an infinite potential well....
