The angle between electric and magnetic field in an electromagnetic wave travelling in vaccum is

If ${\epsilon }_0$ and ${\mu }_0$ are the electric permittivity and magnetic permeability in free space, $\epsilon$ and $\mu$ are the corresponding quantities in a medium, then index of refraction of the medium is

$\mathrm{X}$-rays are used as a tool to study the properties of single crystals, since
