Vedclass · Answer

(D) Maxwell deduced that the speed of propagation of an electromagnetic wave through a vacuum is determined by the permeability of free space $\mu_0$ and the permittivity of free space $\epsilon_0$ as follows:$c = \frac{1}{\sqrt{\mu_0 \epsilon_0}}$Substituting the values $\mu_0 = 4\pi 	imes 10^{-7} \, 	ext{T m/A}$ and $\epsilon_0 \approx 8.854 	imes 10^{-12} \, 	ext{C}^2 	ext{N}^{-1} 	ext{m}^{-2}$ yields the speed of light $c \approx 3 	imes 10^8 \, 	ext{m/s}$.
