Question

EM Wave Direction 03 022 10.0 poin Consider an electromagnetic wave pattern as shown in the figure below. 2 direction If the wave is traveling right to left (as shown) and at a particular instant of time, the B vector is along the negative y direction, in what direction is the corresponding E field at that time? 1. Cannot be determined since the wave shown in the figure is a standing wave and is stationary 2. The E vector is along the negative 2 direction. 3. The E vector is along the positive z di- rection.

Explanation / Answer

E vector will be in negative z direction.

it can be determined from the fact that vector product of E vector and B vector gives the direction of propagation. so by right hand rule we can find direction of E vector.
