Electric and magnetic fields of EM waves are:

Question

The electric field in a plane electromagnetic wave is given by \(E_z = 60 \cos(5x + 1.5 \times 10^{10} t)\) V/m. Then expression for the corresponding magnetic field (\(B_y\)) is (here subscripts denote the direction of the field) is:

Answer 1

Electromagnetic waves feature perpendicular oscillating electric (E) and magnetic (B) fields that are also perpendicular to the direction of wave travel. These fields oscillate in unison.
