论文部分内容阅读
高中物理光学主要介绍了光的传播、光的波动性和粒子性,这部分涉及的物理量和概念较多,关系较复杂又难理解,若要学好这部分内容必须把握好光学的知识结构和脉络,弄清各物理量间的关系.因此,学好光学中的两个典型实验是关键.下面笔者对这两个实验做一小结,结合实例介绍它在解决实际问题中的应用,以期与同行交流,共同提高.一、两个“平行”实验的结论1.实验一:光的色散实验光的色散实验不仅证明了光是一种复合光,同时也说明了不同色光在同种介质中的折射率是不同的.之所以不同色光的折射率不同,是因为不同色光在同种介质中的传播速度不同,由 n=c/v 可知,在同种介
High school physics optics mainly introduces the spread of light, the fluctuation of light and particle. This part involves more physical quantities and concepts, the relationship is complicated and difficult to understand. To learn this part, we must grasp the structure and context of optical knowledge , To understand the relationship between the physical quantities.Therefore, learn two typical experiments in optics is the key.After I make a brief summary of these two experiments, with examples of its application in solving practical problems, with the exchange of peers, One, two “parallel ” conclusion of the experiment 1. Experiment one: light dispersion Experimental light dispersion experiment not only proved that light is a composite light, but also shows the different shades of light in the same medium The refractive index is different.The reason why different shades of the refractive index is different because different shades of light in the same medium in different speed of transmission, from n = c / v shows that in the same kind of medium
