Question

speed of light in terms of electric and magnetic constants​

Answer 1

$c = \sqrt{ \frac{1}{ \mu \epsilon} }$

Answer 2

Answer:

The speed c of an electromagnetic wave is determined by the constants of electricity and magnetism that you know so well: c = 1/(e0m0)1/2 = 2.998 X 108m/s. .

.. If the wave moves in z-direction, and the electric field oscillates in the x-direction, then the magnetic field oscillates in the y-direction.
