高二物理(必修)“测定玻璃的折射率”实验通常用针插法来确定入射光线和出射光线,然后利用作图的方法确定折射光线,最后进行数据的计算与处理。在数据处理时可以采用以下方法:1 角度测量法这是教材中采用的方法,在用针插法确定出入射光线和出射光线并利用作图确定出折射光线后,通过入射光线与介质界面的交点做入射广线和折射光线的法线,从而确定出入射角和折射角,用量角器量出,根据折射定律计算出玻璃的折射率。
Sophomore physics (required) “Measurement of the refractive index of glass” experiments usually use pin-inserting methods to determine the incident light and outgoing light, and then use the mapping method to determine the refracted light, and finally perform data calculation and processing. In the data processing can use the following methods: 1 Angle measurement This is the method used in the teaching materials, in the use of pin interpolation to determine the incident light and exit light and use the mapping to determine the refracted light, through the incident light and the media interface The intersections are made normal to the incident wide line and the refracted ray, so that the incident angle and refraction angle are determined. The protractor is used to measure the refractive index of the glass according to the law of refraction.
