Question

How is the speed of em-waves in vacuum determined by the electric and magnetic fields?​

Answer 1

Answer:

$\Large\underline{\underline{\sf{ \color{green}{\qquad Answer \qquad} }}}$

Speed of em-waves in vacuum is determined by the ratio of the peak values of electric and magnetic field vectors.

I ,e C = $\frac{E_o}{E_o}$

Answer 2

$hello$

The speed of the em-waves in a vacuum is determined by the ratio of the peak value of electric and magnetic fields.

Merry Christmas ⛄

I hope my answer helps you......✌
