Refraction is the phenomenon of bending of light at the boundary of two mediums. Refraction is caused due to the change in speed of light when it enters from one medium to another. when light goes from water to air it bends away from the normal because three is an increase in speed of light.

Reflection occurs because the EM field of the incoming radiation causes oscillations in the electrons of the substrate, making them each secondary emitters of radiation.
