For an electromagnetic wave in free space having an $\vec { E }$ field of amplitude E₁ and a $\vec { B }$ field of amplitude B₁,the ratio of B₁/E₁ is equal to A)c B)c² C)1/c D)1/c² E) $\sqrt { c}$

Question

Quizplus · Accepted Answer

The ratio of the electric field amplitude to the magnetic field amplitude for an electromagnetic wave in free space is given by c, the speed of light. Therefore, B₁/E₁ = 1/c.
