The "wetting" that happens when an object is immersed in a liquid depends on the surface energy of the object and the capilary forces in action on the surface of the liquid. for example mercury will not "wet" glass but water can wet the same glass.
What happens to the light that doesnt go through glass?
When light hits glass: -- some of it bounces off the glass surface and goes back away from the glass (reflection) -- some of it is absorbed into the glass and never heard from again (absorption) -- some of it goes through the glass and comes out the other side (transmission).
Why does a glass tumbler crack when you suddenly pour hot tea into it?
When we pour very hot water into an empty glass, the inner surface of the glass will expand as matter expands when heated. But the inner surface of the glass will expand more than the outer surface of the glass because more heat is applied to the inner surface of the glass.

they are reflected at an equal opposing angle on a first-surface mirror. on a second surface (bathroom mirror) they are also reflected, but some are absorbed/disbursed by impurities and inconsistencies in the glass.
