I like to know if electromagnetic waves pass through a medium (Glass) and if this medium were in contact with two other mediums in its boundary which the first one with same optical dense (Glass) and the second with less optical dense (air). Is there any tendency or priority for wave to pass...

Thank you, I have already read that webpage. I need more information.

I like to know some concept about ball lenses (spherical lenses) specially when they are in contact with each other. I googled it but nothing. I will really be thankful if anyone can help me.
