Therefore, to tell a little about the history of physics is also one of the measures in accordance with the direction of physics teaching reform. Geometric optics is based on the laws of reflection and the laws of refraction. It took more than 1 thousand years for people to explore the ...

Mirages may have had an effect on history: a World War Ⅰ story, which has not been really verified( 考证 ), deals with a crucial( 决定性的 ) battle between the Turks and the British. Supposedly, the stronger Turkish army was gaining the advantage when one of its outposts reported ...
The meaning of REFRACTION is deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (such as air) into another (such as glass) in which its velocity is different. Did you know?
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 asphalt-surfaced(沥...
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
Refraction of Light When a ray of light traveling through a transparent medium encounters a boundary leading into another transparent medium, part of the ray is reflected and part of the ray enters the second medium. The ray that enters the second medium is bent at the boundary. This bending...
