A plane electromagnetic wave travels in vacuum along z-direction. What can you say about the direction of electric and magnetic field vectors?

Text Solution

Verified by Experts

In e.m. wave the elctric and magnetic field
vectors are perpendicular to each other and also
perpendicular to the direction of propagation of
e.m. wave. As plane e.m. wave is propagating
along z-axis, so the electric field vector is along
x-axis and magnetic field vector is along y-axis.
