The question becomes much more interesting when you consider the shore on a circular island. The water waves are slowed and refracted as they enter the shallower zone near the shore and the refraction continues all the way around the island. The

How would we otherwise have a real sense, what near to us and what farther away is?! Thanks to this “illusion”, we can truly perceive the reality. The “illusion” with
