Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 9A An electromagnetic wave in vacuum is moving in the positive z direction. a. At a particular time t and at a particular position, the electric field component of this wave is 10.0 V/m and is pointing in the positive y direction. In what direction is the magnetic field component pointing at that time and position? What is the magnitude of this magnetic field? b. If (10.0 V/m) happens to be the maximum magnitude of the wave's electric field, what is the wave's intensity?
