The ratio of the magnitude of the magnetic field and electric field...

The ratio of the magnitude of the magnetic field and electric field intensity of a plane electromagnetic wave in free space of permeability μ0\mu_0 and permittivity ε0\varepsilon_0 is (Given that cc - velocity of light in free space):

Options

  1. Acc
  2. B1c\frac{1}{c}
  3. Ccμ0ε0\frac{c}{\sqrt{\mu_0 \varepsilon_0}}
  4. Dμ0ε0c\frac{\sqrt{\mu_0 \varepsilon_0}}{c}

Correct answer

B. 1c\frac{1}{c}

Step-by-step solution

As per question, B0E0=1c=μ0ε0\frac{\mathrm{B}_0}{\mathrm{E}_0}=\frac{1}{c}=\sqrt{\mu_0 \varepsilon_0} (where, the symbols have their usual meanings.)
