Those collisions divert the light, lengthening the distance it travels through something like 1 cm of glass vs 1 cm in a vacuum. It changes the time it takes to travel through glass rather than the speed at which the light is moving. At least that's what I remember from a YouTube video. permalink fedilink source parent hideshow 2 child comments replies: [–] xx3rawr@sh.itjust.works 5 points 2 years ago (1 child) Probably the Youtube video in question permalink fedilink source parent hideshow 2 child comments replies: [–] tacosplease@lemmy.world 4 points 2 years ago Yes that's it!
