. A plane electromagnetic wave propagating along x-direction can have the following pairs of E and B a) Ex, By b) Ey, Bz c) Bx, Ey d) Ez, By
Correct option is D) Let us consider, in electromagnetic wave x,y, and Z axis are there. By using Right Hand Rule, Ey×Bz=Vx By using Right Hand Rule EZ×BY=−Vx So, from above two condition there is a possible of two condition there is a possibility of two pairs in which wave can propagate in +ve direction and in second condition it can propagate in -ve x-axis.
