The velocity of electromagnetic radiatior in a medium of permittivity `epsilon_(0)` and permeability `mu_(0)` is given by

Options

A. `sqrt((epsi_(0))/(mu_(0)))`
B. `sqrt(mu_(0)epsi_(0))`
C. `(1)/(sqrt(mu_(0)epsi_(0)))`
D. `sqrt((mu_(0))/(epsi_(0)))`

Answer

C

Explanation

Velocity of electromagnetic radiation is the velocity of light (c), ie
`c=(1)/(sqrt(mu_(0)epsi_(0)))`
where `mu_(0)` is the permeability and `epsi_(0)` is the permittivity of free space.
