CONCEPT:

  • The electric field is always perpendicular to the magnetic field, and both fields are directed at right-angles to the direction of propagation of the wave.
  • The wave propagates in the direction E × B. Electromagnetic waves are a type of transverse wave.

 

F1 J.K Madhu 28.05.20 D15

EXPLANATION:

  • In electromagnetic waves the electric field is always perpendicular to the magnetic field and both field are directed at right –angles to the direction of propagation of the wave.

So option 4 is correct.
