Question

The speed of light is vacuum is equal to

• A. $\frac{1}{\sqrt{\mu_0 \varepsilon_0}}$
• B. $\mu_0^2 \varepsilon_0^2$
• C. $\sqrt{\mu_0 \varepsilon_0}$
• D. $\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}$

Answer 1

Answer: (A)

$\frac{1}{\sqrt{\mu_0 \varepsilon_0}}$

Answer 2

The speed of light in the vaccum is given by the formula $C=\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}$ where, $\mu_{0}=$ permeability of vacuum or air $\varepsilon_{0}=$ permittivity of air.
