Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, the electromagnetic waves constituting light are refracted when crossing the boundary from one transparent medium to
GiftedHistoryTrend AnalysisThe author introduces the special issue on the last 25 years of gifted education by reviewing problems (such as persistence of myths) and high marks in the field (such as the development of advocacy groups). (CL)...
答案:1A2B3D4C提示:1.A Mirages(海市蜃楼) are produced by refraction(折射) of light within a layer(层), or lens(透镜), of air. 所以本题选A. 2.B The easiest form of mirage to study, however, is one that has been seen by millions of people—those seeming strips(条状) of water on...
