某杂志有一篇《用玻璃砖观察光的色散》的文章,读后颇受启发。但对原文的看法,笔者不敢苟同,因通过长方形玻璃砖两平行侧面观察物体,并没有看到物体的边缘出现彩色,这说明并没有发生色散现象。下面通过计算分析来验证一下未发生色散的原因。原文中因各色光在玻璃中折射率不同,经过折射,将使其分开,所以阳光通过长方形玻璃砖的两个平行面,将能观察到明显的色散现象。其实,我们 A magazine has an article titled “Dispersion of Light Observed with Glass Tiles.” It was inspired after reading. However, the author did not dare to agree with the view of the original text, because observing the object through two parallel sides of the rectangular glass brick did not see the color of the edge of the object, indicating that no dispersion occurred. The following calculation and analysis to verify the cause of the dispersion did not occur. In the original text, because of the different refractive indices of different colored light in the glass, they will be separated by refraction. Therefore, the sunlight will pass through the two parallel faces of the rectangular glass block, and obvious dispersion will be observed. In fact, we
