Suppose that you look at an aquarium with your eyes at the lever of the water surface. A duck swims on the surface of the water. When you look at the duck from the front, everything seems normal. However, when you look at the duck at an angle to the glass surface, the duck seems to be spilt in half, with the feet paddling ahead of the upper body. Explain this phenomenon.
(I know this has to do with refraction, but how can I explain that?)
Suppose that both the duck and your eyes are at a distance of 1m from the glass, and the line connecting them forms a 30 degree angle with the glass. Calculate the difference between the directions of the line of sight of the upper and lower halves of the duck.
(I know I am not following the rules very well, but I am really not understanding this phenomenon.)
