The amplitude of the electric field is $0.012~V/m$ The frequency of the electric field is $120~GHz$
We can find the amplitude of the electric field: $E = c~B$ $E = (3.0\times 10^8~m/s)~(4.00\times 10^{-11}~T)$ $E = 0.012~V/m$ The amplitude of the electric field is $0.012~V/m$ Since the frequency of the electric field is the same as the frequency of the magnetic field, the frequency of the electric field is $120~GHz$
