句子

We treat light beams as rays that propagate along straight lines, except at interfaces between dissimilar materials, where the rays may be bent or refracted. This approach, which had been assumed to be completely accurate before the discovery of the wave nature of light, leads to a great many useful results regarding lens optics and optical instruments.

我们将光束处理为沿着直线传播的光线，除了在不同材料之间的界面处，其中光线可以被弯曲或折射。这种方法被认为在发现光的波特性之前是完全准确的，导致产生许多关于透镜光学和光学仪器的有用结果。

When a light ray strikes a smooth interface between two transparent media at an angle, it is refracted.

当光线以一个角度撞击在两个透明介质之间的平滑界面时，其为折射。

The refractive index of a given material is not independent of wavelength, but generally increases slightly with decreasing wavelength.

给定材料的折射率并非与波长无关，但通常随着波长减小而略微增加。

A word of warning with regard to the signs in algebraic expression: Because of the sign convention adopted here, derivations based solely on geometry will not necessarily result in the correct sign for a given term. There are two ways to correct this defect. The first, to carry a minus sign before the symbol of each negative quantity, is too cumbersome and confusing for general use. Thus, we adopt the second, which is to go through the final formula and change the sign of each negative quantity. This procedure has al ready been adopted in connection with the “len” equation and is necessary, as noted, to make the formula algebraically correct. It is important, though, not to change the signs until the final step, lest some signs be altered twice.

关于代数表达式中的符号的警告词：由于这里采用的符号法则，仅基于几何的导出不一定导致给定术语的正确符号。有两种方法来纠正此缺陷。第一，在每个负数量的符号之前携带减号，对于一般使用来说太麻烦和混乱。因此，我们采用第二个，即通过最后的公式，并改变每个负数量的符号。这个程序已经结合“len”方程被采用，并且如上所述是必要的，以使公式在代数上是正确的。然而，重要的是，不要改变迹象，直到最后一步，以免一些迹象改变两次。

When conditions are such that the light is incoherent, it is not possible to detect interference effects. A discussion of wave optics is incomplete without considering the conditions that must exist for an interference experiment to be performed successfully. 当条件使得光不相干时，不可能检测干涉效应。波光学的讨论是不完整
