Question

Which wave relation follows from Maxwell’s equations for the plane electromagnetic wave?

Options

• \[\omega=k/c\]

• \[\omega=\nu\lambda\]

• \[\omega=ck\]

• \[\omega=c/k\]

Answer 1

Maxwell’s equations give \[\omega=ck\] for these electric and magnetic fields. The angular frequency is proportional to the magnitude of the wave vector.
