Unformatted text preview: ld in the region where the electric field is nonzero, what would be the direction of the magnetic field? 007 (part 3 of 3) 10.0 points Find Bz . y 3 t1 x What is the direction of propagation of the electromagnetic wave? Choose the unit vector corresponding to this direction. 2. 0, 1, 0 3. 1, 0, 0 4. 0, 0, 1 5. 0, 0, −1 correct 6. 0, −1, 0 Explanation: We know that E × B points in the direction of propagation. Pointing your thumb along the −y axis to indicate the direction of propagation and pointing your fingers along the −x direction to indicate the direction of the electric field, the right-hand rule indicates that the magnetic field must point along the −z axis. 010 (part 1 of 2) 10.0 points A pulse of electromagnetic radiation is propagating in the +y direction. You have two devices that can detect electric and magnetic fields. You place detector 1 at location 1. −1, 0, 0 2. 0, 0, −1 0, −5, 0 m and detector 2 at location 0 , 5 , 0 m. 3. 0, 1, 0 4. 0, −1, 0 correct 5. 0, 0, 1 6. 1, 0, 0 Exp...
