目前的中学物理课教学大纲中，光学知识和光学实验所占的比例都不大，却不可忽视。因为不仅在自然界和生活中存在着五彩缤纷的光学现象，而且现代技术的发展也越来越多地应用到光学检测、激光加工、激光通讯等手段，同时创造出许多光机电一体化的产品，例如ＶＣＤ机。由于光会 In the current syllabus for middle school physics, the proportion of optical knowledge and optical experiments is not large, but it cannot be ignored. Because there are not only colorful optical phenomena in nature and life, but also the development of modern technology is increasingly applied to optical detection, laser processing, laser communication and other means, and at the same time creating a number of optical and electromechanical integration products, such as VCD machine. Because the light will
