The amplitude of the magnetic field part of a harmonic electromagnetic wave in vacuum is `B_(0) = 510 nT`. What is the amplitude of the electric field part of the wave?

Explanation

During the propagation of electromagnetic wave in vacuum if amplitudes of electric and magnetic field are respectively `E_(0)` and `B_(0)`, then
`c=(E_(0))/(B_(0))`
`therefore E_(0)=B_(0)c`
`=(510xx10^(-9))(3xx10^(8))`
`=1530xx10^(-1)`
`therefore E_(0)=1.53xx10^(2)Vm^(-1) (or NC^(-1))`
