Asked by: Jennifer Answer Jennifer, to completely answer your question, we need to know a little about the sun & a little about glass properties. Let start with the sun. Now we have to also note that, along with red, yellow & blue, the sun emits radiation that is not visible & part of it is called ultraviolet (UV). Now about the glass. The glass simply filters out the UV radiation that is responsible for the sunburns & protect your skins from these energetic & somewhat harmful radiation. Answered by: Gilles Lalancette, M.S., Physicist, Dorval, Québec, Canada You can, actually; it depends on the glass. We know that electrons in any molecule can only absorb radiation at certain frequencies. The upshot, though, is that glass should shield you from most of the harmful UV radiation running around out there. Answered by: Rebekah Cowdrey, Physics Undergrad Student, U.
