Does Wave Refraction Change Wave Direction or Alignment

[Tom MS]

I can't seem to find anything online that talks about this distinction. I understand how when the water gets shallower that part of the wave gets slowed down so the overall alignment parallels with the shore. However, I wouldn't think that would change the actual direction of the wave. I need a detailed explanation on why I'm probably wrong.

The energy is flowing at right angles to the alignment. In this respect, your diagram is incorrect on the sides of the promontory.

The alignment and the direction of the wave are the same thing.

It is identical to light going through a medium like glass.

I was talking about the alignment of the crest relative to the shore and the direction that the wave form traveled.

Yes, and they are the same thing. Waves travel orthogonal to their crests/wavefronts.
