1. The problem statement, all variables and given/known data
What is the magnetic field amplitude of an electromagnetic wave whose electric field amplitude is 100V/m?

2. Relevant equations
Eo=Bo*c

3. The attempt at a solution

100/(3*10^8) = .0000003

Mastering physics says this is wrong though ^^
