Unformatted text preview: brown (twb493) reflection 5 chiu (56565) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 5) 10.0 points 1. In which direction do the electromagnetic waves propagate? 1. + y 2. Away from the source 3. Along the direction of the source charge oscillation 4. Towards the source 5. + x 6.- z 7. Perpendicular to vector E vector B 002 (part 2 of 5) 10.0 points Classically, what happens to the velocity of the positron when subjected to the radiation fields? (Set relfactor = 1.) If you wish to view the velocity in units of c , you may want to divide the velocity by c before the print statement in the loop. 1. It approaches 2 c . 2. It grows without bound. 3. It varies between values close to 0 and values close to c . 4. It approaches c . 5. It approaches c/ 2. 003 (part 3 of 5) 10.0 points Relativistically, what happens to the velocity of the positron when subjected to the radia-...
