A uniform plane electromagnetic wave traveling in free space enters into a lossless medium at normal incidence. In the medium its velocity reduces by $50 \%$ and in free space sets up a standing wave having a reflection coefficient of $0.125$. Calculate the permeability and the permittivity of the medium.
