Glass Transmitting

Would a piece of glass transmit infrared light?

Why or why not?

Absorption of radiation by a medium, by definition, necessitates an inelastic interaction within it, such as electric field induced conduction band electron acceleration/scattering and/or molecular excitation. The electrons in glass are bound too tightly for either for photons in the IR. Once you get into the UV, the photons approach electron orbital resonances, and you get absorption. For soft X-rays (also called “vacuum UV” since it requires vacuum to transmit), molecules are ionized by the photons, and even air becomes opaque.
