The amplitude of the magnetic field part...

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?

Text Solution

Verified by Experts

We are given: `B_(0)= 510nT= 510 xx 10^(-9) T`
We are to calculate, `E_(0)`
Using relation `c= (E_(0))/(B_(0))`
we get, `E_(0)= c.B_(0) =3 xx 10^(8) xx 510 xx 10^(-9) = 153 N//C`
