Electro magnetic waves travel in a mediu...

Electro magnetic waves travel in a medium with speed of `2xx10^(8)m//sec`. The relative permeability of the medium is `1` find relative permittivity.

Text Solution

Verified by Experts

Given `C=2xx10^(8)m//sec`, `mu_(r)=1`
Speed of `EM` waves in medium
`C_(med)=(1)/(sqrt(mu_(r)mu_(0)epsilon_(r)epsilon_(0)))=(C_(0))/(sqrt(mu_(r)epsilon_(r)))`, `epsilon_(r)=(c_(0)^(2))/(c^(2)mu_(r))=((3xx10^(8))^(2))/((2xx10^(8))^(2)xx1)=2.25`
