deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (as air) into another (as glass) in which its velocity is different
Layer of air at different temperatures refracts ("bends") light at different angles. Cold air is more dense than warm, and refracts light at a greater angle. Actually, it is the boundary between layers that does the refracting--poke a stick into a pool of water [or a pencil into a bowl of water] and observe the "broken" appearance. In the atmosphere, this can cause an image to appear "above" its actual location, usually upside down.
