查询词典 refraction

It still remains to be shown how the wave theory explains the refraction of light and the variety of colours. The corpuscular theory is capable of this, as we know.

我们还需要说明光的波动说怎样去解释光的折射和色的多样性，我们知道光的微粒说能够作出这种解释。

Thus we see that not only the corpuscular theory, but also the wave theory, leads to an explanation of refraction.

由此可见，不仅光的微粒说，而且光的波动说也可以解释折射。

At all angle s less than the critical angle , both reflection and refraction occur.

对于所有小于临界角的入射角，则既发生反射，又发生折射。

At all angles less than the critical angle, both reflection and refraction occur.

对于所有小于临界角的入射角，则既发生反射，又发生折射。
