Express velocity of electromagnetic wave...

Express velocity of electromagnetic wave in a material medium in terms of `mu` and `epsi`.

A

`(1)/(muepsilon)`

B

`(1)/(2muepsilon)`

C

`(1)/(sqrt(muepsilon))`

D

`(1)/(sqrt(2muepsilon))`

Text Solution

Verified by Experts

The correct Answer is:
C
The speed of an electromagnetic wave in a medium,
`v=(1)/(sqrt(muepsilon))`
where `mu` and `epsilon` be permeability and permittivity of the medium respectively.
