Why does the ocean look like its not moving from an airplane?


  • Q :  When I went to Hawaii a while ago, i looked out the window of the plane and saw that the ocean and the waves didn't look like they were moving! The were just frozen in place, when i know that they actually are moving. Why does it look like that?
  • A : Yep, its cause you are far away. The same thing happens when you look out the window at something far away (like a mountain or tree) when you are driving in a car. Because of the distance your eye sees what appears to be slower or "frozen" waves, this happens because everything seems smaller the further away you get from it, so your brain compares the movement of the waves against these (perceived) smaller things (rocks, the beach) and as a result it appears as if the waves are covering less distance.
