Question 208: EM waves

Question

The ratio of amplitude of magnetic field to the amplitude of electric field for an electromagnetic wave propagatting in vacuum is equal to

Accepted Answer

If the speed of light c then
E
0
= B
0
c
$$ \Rightarrow $$ $${{{B_0}} \over {{E_0}}} = {1 \over c}$$
Hence ratio of amplitude of magnetic field to amplitude of electric field for electromagnetic wave in a vacuum is reciprocal of speed of light.

Answer

the speed of light in vacuum
