Hi,
When exactly does the phase change of [tex]\pi[/tex] occur when a EM wave reflects from a surface? I notice that it happens in Lloyd's mirror for example, and also when considering non reflective coatings on lenses. Is it just when the EM wave is going into a medium with higher refractive index or is there more to it than that?
Thanks
