Expert Answer:

In refraction , bending of a ray of light (form its original path) takes place , as it passes from the first medium to the second medium whereas in case of reflection , light ray falling on the boundary seperating two media is sent back into the first (same) medium

speed of light doesn't change after reflection whereas it may change after refraction (depending upon the refractive index of second medium.
