-
The electric and magnetic field of an electromagnetic wave are
-
- in opposite phase and perpendicular to each other
- in opposite phase and parallel to each other
- in phase and perpendicular to each other
- in phase and parallel to each other.
Correct Option: C
Variation in magnetic field causes electric field and vice-versa. In electromagnetic waves, Ê ⊥ B̂ Both Ê and B̂are in the same phase.
In electromagnetic waves
E = E0 sin(ωt - kx)
B = B0 sin(ωt - kx)
The electromagnetic waves travel in the direction of
(→
E →
B)
