Vedclass · Answer

(D) The relationship between the magnitude of the electric field $(E)$ and the magnetic field $(B)$ in an electromagnetic wave is given by the equation: $E/B = c$,where $c$ is the speed of light in vacuum.Given: $E = 6.6 \,V \,m^{-1}$ and $c = 3 	imes 10^8 \,m \,s^{-1}$.Rearranging the formula to solve for $B$: $B = E/c$.Substituting the values: $B = 6.6 / (3 	imes 10^8) \,T$.Calculating the result: $B = 2.2 	imes 10^{-8} \,T$.Therefore,the correct option is $D$.

For a given electromagnetic wave,the magnitude of the electric field is $6.6 \,V \,m^{-1}$ at a point in space. The magnitude of the magnetic field at this point is . . . . . . $T$.
