In a plane electromagnetic wave, the electric field oscillates sinusoidally at a frequency of $2.5\times 10^{10} \mathrm{H}\mathrm{z}$ and amplitude $480 \mathrm{V} {\mathrm{m}}^{-1}$. The amplitude of the oscillating magnetic field will be

• A

  $\text{1.52}\times {10}^{-8} \mathrm{Wb} {\mathrm{m}}^{-2}$
• B

  $\text{1.52}\times {10}^{-7} \mathrm{Wb} {\mathrm{m}}^{-2}$
• Correct answer
  C

  $\text{1.6}\times {10}^{-6} \mathrm{Wb} {\mathrm{m}}^{-2}$
• D

  $\text{1.6}\times {10}^{-7} \mathrm{Wb} {\mathrm{m}}^{-2}$

Hence, the correct answer is option: 'C'.
