Damn son, flatearthception.

Also, technically refraction has nothing to do with reflecting.

the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.

change in direction of propagation of any wave as a result of its traveling at different speeds at different points along the wave front.

All it can do is bend it one way or the other, its not actually reflecting anything.
