english: Because light is a wave, two different frequencies shouldn't interact with each other at all, they should just co-exist like singers singing in harmony.
non_english: Pretože svetlo je vlnou,  dve rôzne frekvencie by sa nemali navzájom vôbec ovplyvňovať, mali by len koexistovať ako speváci, ktorí spievajú v harmónii.
