For plane electromagnetic waves propagating in the positive Z - direction. The combination which gives the correct possible direction for E and B fields respectively is
Options
- A(-2 i-3 j) and (3 i-2 j)
- B(3 i+4 j) and (4 i-3 j)
- C(i-2 j) and (-2 i-j)
- D(-2 i+3 j) and (i+2 j)
Correct answer
A. (-2 i-3 j) and (3 i-2 j)
Step-by-step solution
As, E B E B =0 aligned & For E =(-2 i -3 j ), B =(3 i -2 j ) & E B =(-2 i -3 j ) (3 i -2 j ) & =(-2)(3)+(-3)(-2)=-6+6=0 aligned
