What molecular arrangment leads to transperency?

From: Sanny on 20 Jul 2010 12:08 We see glass is transparent. When light touches a surface it gets absorbed and reflected. But in case of glass the light goes inside it and comes out from other end. Earlier I made a guess the number of molecules in glass blocking the light will be less. But then I found some 1 feet thick glass are transparent. While even a 1mm thick aluminium plate do not allow to pass the light. So number of molecules stopping light do not effect whether a substance is transparent or not. I think its the arrangment of molecules that descide wether the substance is transparent or not. Does Glass molecule acts like a spring? and Just like a Spring allows waves to travel through it. Glass allows light wave to pass. What type of arrangment of molecules lead to transparency? Bye Sanny Chat with Physics Professor: http://www.getclub.com/chat_with/?key=Physics

These interactions depend on the nature of the light (its wavelength, frequency, energy, etc.) and the nature of the material. Light waves interact with an object by some combination of reflection, and transmittance with refraction".
