Electromagnetic Waves as Sinusoidal Waves Video Lessons

Concept

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
