Unformatted text preview: answer: −9.5 × 10−6 T. Explanation: We know that the magnetic field points along the −y axis, so we just need to find the magnitude, which we can do using E E c= 2 , . c= B B we can write E E =c B = (3 × 108 m/s)(4.3 × 10−5 T) = 12900 N/C . B= c 2850 N/C = 3 × 108 m/s = 9.5 × 10−6 T . dedow (kfd235) – Ch24-h1 – turner – (56525) So the y component is −9.5 × 10−6 T . Correct answer: 0 T. Explanation: See the explanation for part 1. 1. −1, 0, 0 008 (part 1 of 2) 10.0 points At a time t0 , an electric field is detected in the region shown on the left diagram in the figure below. The electric field is zero at all other locations. At a later time t1 , an electric field is detected in the region shown on the right diagram. The electric field is still zero elsewhere. You conclude that an electromagnetic wave is passing through the region. The +z direction points out of the page (toward you). t0 y x netic wave is propagating in the −y direction. 009 (part 2 of 2) 10.0 points If you were to measure the magnetic fie...
