借助平板电脑/智能手机演示平方反比定律
Demonstration of the Inverse Square Law with the aid of a Tablet/smartphone
摘要：
本文介绍了如何用一种简单、快速、高精度的方法求出小光源发出的光强与距离的平方反比定律。借助两部智能手机、免费应用程序和一把尺子，您可以测量列出的设备之间的距离（一个作为光源，另一个作为测量光强度）以及设备中的prowaree测量的相应光强度。所提议的实验易于再现，以及学生和教师中平板电脑和智能手机的普及使用，可以使所提议的活动成为引入表现出相同功能依赖性的物理现象的良好替代方案，例如牛顿万有引力定律和库仑定律。
英文摘要：
In this paper we show how to obtain the Inverse-square law of the distance to the light intensity emitted from a small source in a simple, fast and with good precision way. With the aid of two smartphones, free apps and a ruler, one is able to measure the distances between the devices listed (one as a source and the other as a measuring light intensity) and the respective light intensities measured by the probeware in the device. The ease of reproduction of the proposed experiment and the penetration of the use of tablets and smartphones among students and teachers, could make the proposed activity a good alternative to the introduction of physical phenomena which exhibit the same functional dependence, such as the Law of Newton's Universal Gravitation and Coulomb's Law.
