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

Options

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

Answer

c

Explanation

Velocity of electromagnetic radiation is the velocity of light `(c)`, i.e.,
`c=(1)/(sqrt(mu_(0)epsilon_(0)))`
Where `mu_(0)` is the permeability and `epsilon_(0)` is the permmittivity of free space.
