The 6 Ways Light Travels Through Glass


Occurs when light travels through glass without being reflected, absorbed or scattered.


Occurs when incoming light hits the glass and bounces off.


Occurs when light waves change direction as they pass from one medium to another.


Refers to the bending and spreading of waves around the glass.


Occurs when photons from light hit atoms and molecules and cause them to vibrate, creating thermal energy.


Occurs when light bounces off of the glass in a variety of directions.


We take pride in offering materials from industry-recognized companies. Below is just some of the many materials that we source. Visit our materials page for a complete list.
