Lensing,caustics and chromatic aberation of sunlight on water in a swimming pool. The rippled surface of the water acts like many small lenses,focussing light onto tiles (caustics),distorting their shape and adding coloured fringes (chromatic aberation). In optics,a caustic or caustic network is the envelope of light rays reflected or refracted by a curved surface or object,or the projection of that envelope of rays on another surface. These curved surfaces act like assymetric lenses focussing the light rays into constantly changing patterns | |
