The electric field ( E0 ) and magnetic field ( B0 ) in a plane electromagnetic wave have a special relationship.
We know that ‌

E0

B0

=c where c is the speed of light, which is 3×108m∕s.
If we compare E0 to 108 times B0, we get: ‌

E0

108B0

=‌

E0

B0

×‌

1

108

Now substitute c for ‌

E0

B0

:‌

E0

108B0

=‌

3×108

108

=3
So, the answer is: ‌

E0

108B0

=3
