In an electromagnetic wave

Question

In an electromagnetic wave (A) power is transmitted along the magnetic field (B) power is transmitted along the electric field (C) power is equally transferred along the electric and magnetic fields (D) power is transmitted in a direction perpendicular to both the fields

Tardigrade Admin · Accepted Answer

For electromagnetic waves vec E and vec B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of vecE × vecB. The direction of propagation of the wave is the direction of propagation of its energy and power.

Q. In an electromagnetic wave

power is transmitted along the magnetic field

power is transmitted along the electric field

power is equally transferred along the electric and magnetic fields

power is transmitted in a direction perpendicular to both the fields

For electromagnetic waves $E$ and $B$ are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of $E \times B$ .
The direction of propagation of the wave is the direction of propagation of its energy and power.
