eli5: why does glass absorb infrared and ultraviolet light, but not visible light?
In: Physics
This isn’t a full answer, more a comment. But if glass didn’t allow visible light through we wouldn’t use it as a window – we’d find some other material. And since we don’t see in infrared or ultraviolet then we don’t care if our windows absorb those frequencies. Glass is a Goldilocks material for this reason.
