Question

How are the magnitudes of the electric and magnetic fields
related to velocity of the em wave?

Zafar · Accepted Answer

For an electromagnetic wave electric and magnetic field is given
by

EX=EOSIN(Kz-ωt) BY=BOSIN(Kz-ωt)where k is related to wavelengthλ as k=2πλit is also seen from maxwell's equations that the magnitude of electric and magnetic fields in an electromagnetic wave are related as BO=EOCWHERE C IS THE SPEED OF ELECTROMAGNETIC WAVE IN VACCUM
