Light and Color Mixing

These are a few exercises to get you to explore the capabilities of the Light Box. The boxes are to be powered from the DC supply terminals on your lab table.

这些练习将帮助你探索光盒的性能。这些光盒应从实验台上直流电源的端子供电。

The instructions are general, so that your team can explore to find a way to accomplish the task with the equipment included.

指令是通用的，因此您的团队可以探索以找到利用所包含设备完成任务的方法。

1. Make a rough determination of the focal lengths of the two converging and one diverging lenses with the symmetric curved edges.

对具有对称曲面边缘的两个会聚透镜和一个发散透镜的焦距进行粗略测定。

2. Devise a lens combination that takes a wide parallel beam of light and converts it into a narrow beam of light, also parallel. Describe the combination you develop, identifying the lenses used and making whatever measurements are needed.

设计一种透镜组合，将一束宽广的平行光束转换为一束狭窄的平行光束。描述你设计的组合，明确所使用的透镜，并进行必要的测量。

3. Examine rays of light through a rectangular strip of clear material . Make a sketch of the directons of the rays.

观察通过矩形透明材料的光线。画出光线的方向。

4. Work your way around the Newton color circle, using the color slides which are a part of the kit. Examine the colors produced when you use colored slides which are two positions apart. In equal mixture, these should give the color between them. Comment on the color you perceive - is it what it is supposed to be?

沿着牛顿色轮绕行，使用套件中的一部分彩色滑片。检查使用相隔两个位置的彩色滑片所产生的颜色。在等量混合时，这些颜色应该位于它们之间。评论你所感知的颜色——它是否如预期那样？

5. Make a rough determination of the focal length of one of the curved mirrors. Then measure the radius of curvature of the mirror. How do they compare (calculate their ratio)?

对其中一个凹面镜的焦距做一个粗略的估计。然后测量该镜的曲率半径。它们之间有什么关系（计算它们的比值）？
