eli5: why does glass absorb infrared and ultraviolet light, but not visible light?
In: Physics
Depends on the glass composition. For instance solar green glass, which is commonly used in automotive applications has a different makeup compared to glass used on a coffee table, or glass used on a skyscraper. Solar green does a nice job blocking some UV and some infrared, and allows for most visible light because that’s what’s required by law and practically what is needed for cars.
All of this can be changed in 3 main ways: change the recipe for the glass, add a piece of laminate between two pieces of glass or add a coating to the glass. That can impact color, light transmission, heat absorption you name it.
