The speed of light in vacuum is equal to

Options

A. `mu_(0)epsilon_(0)`
B. `mu_(0)^(2)epsilon_(0)^(2)`
C. `sqrt(mu_(0)epsilon_(0))`
D. `(1)/(mu_(0)epsilon_(0))`

Answer

C

Explanation

The speed of light in the vaccum is given by the formula
where `mu_(0)` = permeability of vaccume or air
`epsilon_(0)` = permitivity of air
