Question:
The ratio of amplitude of magnetic field to the amplitude of electric field for an electromagnetic wave propagating in vacuum is equal to the speed of light in vacuum, the ratio of magnetic permeability to the electric susceptibility of vacuum, the reciprocal of speed of light in vacuum, or unity.
the ratio of magnetic permeability to the electric susceptibility of vacuum.
the speed of light in vacuum.
unity.
reciprocal of speed of light in vacuum.
Solution:
We know that, c = E₀/B₀, where c is the velocity of light. Therefore, B₀/E₀ = 1/c
