Problem

The electric field amplitude of a plane electromagnetic wave in vacuum is

120\,\text{V m}^{-1}

. Take

c = 3.0 \times 10^{8}\,\text{m s}^{-1}

. Calculate the corresponding magnetic field amplitude

B_0

. a)

6.4 \times 10^{-8}\,\text{T}

4.0 \times 10^{-7}\,\text{T}

2.0 \times 10^{-7}\,\text{T}

4.0 \times 10^{-6}\,\text{T}
