我们从来到这个美妙世界的那一刻起,无时无刻不在与光接触,同时也或多或少地受到一些非科学观点的影响,从而导致了一些错误的出现.下面就列举一些常见的“光现象”错误,供同学们学习时参考.易错点1:不理解小孔成像的原理和特点.(1)成像原理:如图1所示,小孔成像是由于光沿直线传播形成的.(2)成像特点:倒立的实像,像的形状与小孔的形状无关.部分同学因对成像的特点不能正确理解而出错.
The moment we came to this wonderful world, all the time with light contact, but also more or less by some non-scientific point of view, which led to some mistakes. Here are some common “light phenomenon Error ”, for students to learn reference error-prone 1: do not understand the principle and characteristics of pinhole imaging (1) imaging principle: as shown in Figure 1, pinhole imaging is due to light along a straight line formed. (2) imaging features: inverted real image, like the shape of the hole has nothing to do some students because of the characteristics of the imaging can not correctly understand the error.
