In an electromagnetic wave, the electric field vector and magnetic field vector are given as E → = E 0 i ^ and B → = B 0 k ^ , respectively. The direction of propagation of electromagnetic wave is along:

Options

  1. A( k ^ )
  2. BJ ^
  3. C( - k ^ )
  4. D( - j ^ )

Correct answer

D. ( - j ^ )

Step-by-step solution

Direction of propagation = E → × B → = i ^ × k ^ = - j ^ .
