Thought about this today and couldnt wrap my head around it. Could it have something to do with particle density?
If it has something to do with the abilty to absorb and reflect it, how does that exactly work?
Thanks in advance!

It has to do with the quantum nature light: energy can only be absorbed in amounts which are fixed.
Glass is unable to absorb / accept optical light, because of its internal (electronic) structure.
Steel is different, it’s electrons can easily absorb light, which is why even thin foils are intransparent .
