Question

Why is there no refraction at a 0 degree angle?

Answer 1

So, the angle of inciden is zero and hence the angle of refraction is also zero. In other words,the ray which is incident normally on the interface between the two different media, propagates un deviated from one medium to other and there is no refraction
