If you walk at a constant pace across a room of known length,your walking speed is the room length divided by the time to cross the room.Now suppose you repeat your walk but briefly stop along the way to interact with people sitting along your path.What effect does this have on your average speed across the room? How is this analogous to light passing through glass? In what way is it not analogous?
