1. Show that a moving region of space in which E = (0, E, 0) , B= (0, -B, 0) and v= (-c,0,0) does not satisfy maxwell's equations and therefore is not a possible configuration of traveling fields.
2. A pulse of radiation propagates with velocity ( 0, 0, -c). The electric field in the pulse is (7.2 * 10^6 , 0, 0) N/C. What is the magnetic field in the pulse ?
Can you solve the numericals explaining the steps?
