The light travel by it's in a straight line in vacuum, but when we see through the glass the glass has a refractive index which slows down the speed of light so when I see through the glass I don't see the actual distance. Moreover, the gases particles has refractive index and slows down the speed of light. Does this mean that I don't see the actual distance?
