प्रश्न
Which relationship correctly links the permeability of free space, the permittivity of free space, and the speed of light?
विकल्प
\[\mu_0 \varepsilon_0 = c^2\]
\[\frac{\mu_0}{\varepsilon_0} = c\]
\[\mu_0 + \varepsilon_0 = c\]
\[\mu_0 \varepsilon_0 = \frac{1}{c^2}\]

उत्तर
The striking relationship is μ₀ε₀ = 1/c², equivalently c = 1/√(μ₀ε₀). This connection links magnetism, electricity, and the speed of light, and becomes especially important when studying electromagnetic waves.
