For example, glass has a refractive index of about 1.5. So, the speed of light in glass is c/1.5 ≈ 200.000 km/s, i.e. 66% of the speed of light in vacuum. permalink fedilink source parent [–] Swedneck@discuss.tchncs.de 1 point 1 year ago (1 child) uranium itself isn't, anything will glow that colour if it undergoes nuclear fission underwater. permalink fedilink source parent hideshow 1 child comment replies: [–] KingGimpicus@sh.itjust.works 1 point 1 year ago Actually uranium is a really bright yellow color.
