Particle refraction

There, it mentions that refraction can be explained by particles, but never explains why. Could it be refering to particle fronts, as in water waves?

There's was a question related to that on a recent test. If light was a particle, would it refract through a prism?

I think I posted in the wrong forum, sorry.
