Physics 9 Fall 2008 Midterm 2 Solutions For the midterm, you may use one sheet of notes with whatever you want to put on it, front and back. Please sit every other seat, and please don't cheat! If something isn't clear, please ask. You may use calculators. All problems are weighted equally. PLEASE BOX YOUR FINAL ANSWERS! You have the full length of the class. If you attach any additional scratch work, then make sure that your name is on every sheet of your work. Good luck! 1. (a) Show the uE and uB, the energy densities of the electric and magnetic elds, are equal to each other in an electromagnetic wave. In other words, show that the wave's energy is divided equally between the electric eld and magnetic eld. (b) What is the total energy density in an electromagnetic wave of intensity 1000W=m2? |||||||||||||||||||||||||||||||||||| Solution (a) The energy density of the electric eld is uE = 02 E2, while the magnetic eld energy density is uB = 12 0B2. In an electromagnetic wave, the electric...
