Vedclass · Answer

(A) The relationship between the amplitude of the electric field $(E_0)$ and the amplitude of the magnetic field $(B_0)$ in an electromagnetic wave is given by the formula: $B_0 = \frac{E_0}{c}$.Given that $E_0 = 60 \ Vm^{-1}$ and the speed of light $c = 3 	imes 10^8 \ ms^{-1}$.Substituting these values into the formula:$B_0 = \frac{60}{3 	imes 10^8}$$B_0 = 20 	imes 10^{-8} \ T$$B_0 = 2 	imes 10^{-7} \ T$.Therefore,the amplitude of the magnetic field is $2 	imes 10^{-7} \ T$.

The amplitude of the electric field in an electromagnetic wave is $60 \ Vm^{-1}$. What is the amplitude of the magnetic field?
