Answer 2

reflection :
when light ray hits a surface it bounces back -this is reflection.
it happens on rough surface and a smooth surface but only one medium.
a reflection in a rough surface reflects light in a non-uniform manner in many directions but the opposite happens in a  smooth surface.

refraction:
when light  changes it direction slightly when it moves from one medium to another is called refraction.
