# Problem: Dielectric breakdown in air occurs when the electric field is approximately 3 × 106 V/m.What would be the peak magnetic field in an electromagnetic wave with this value for its peak electric field?

###### FREE Expert Solution

Speed of light, electric field and magnetic field are related as

$\overline{){\mathbf{c}}{\mathbf{=}}\frac{\mathbf{E}}{\mathbf{B}}}$

c = 3.0 × 108 m/s
