Question:

What is the maximum electric field strength in an electromagnetic wave that has a maximum magnetic field strength of {eq}5.00 \times 10^{-4}\ T {/eq} (about {eq}10 {/eq} times the Earth's)?

Electric and Magnetic Fields:

In electromagnetic waves, the maximum electric and magnetic fields can be related together by a simple equation that is written as:

{eq}\displaystyle E = cB {/eq}

where:

  • E is the electric field
  • c is the speed of light
  • B is the magnetic field strength
