Question

Proof electric and magnetic fields are perpendicular

Answer 1

Answer:

For the scalar product between two vectors to be zero either one of them is the zero vector or they are perpendicular to each other. Therefore, the electric and magnetic fields are perpendicular. For a propagating EM wave, the E and B fields are always perpendicular in a homogenous, linear, anisotropic medium.
