  6. Huygensi konstruktsioon õhk Isotroopne keskkond Lainefront on risti valguskiirega ehk kS

  7. õhk anisotroopne keskkond ebatavaline kiir 1. Lainefront ja kiir ei ole risti ehk lainevektor ja Poyntingi vektor ei ole paralleelsed 2. Murduv kiir on langemistasandis vaid juhul, kui optiline telg on langemistasandis

  8. O’ O Anisotroopses keskkonnas levib üldjuhul kaks kiirt eri suundades ja nad on lineaarselt polariseeritud risttasandites. Murduv kiir jääb langemistasandisse vaid juhul, kui optiline telg on ka langemistasandis.

  9. Lained levivad samas suunas, kuid erineva kiirusega; tekib faasinihe
