光线射向平行玻璃板,经两次折射后其出射光线方向不变,仍与原来的方向相同(平行),但产生了一定距离的侧移。在近年高考中呈现出以下几种类型的考题,现归类分析如下:一、直接考查平行玻璃砖的光学特性例1:(2001年高考江浙卷22题)如图所示,两块同样的玻璃直角三棱镜ABC,两者的AC面是 The light is directed at the parallel glass plate, and the light emerges unchanged after being refracted twice, still in the same direction (parallel) as the original direction, but a certain distance of side shift occurs. In recent years, college entrance examination showed the following types of test questions, are now classified as follows: First, direct examination of the optical properties of parallel glass brick Example 1: (2001 college entrance examination Jiangsu Volume 22 questions) As shown, two identical glass Right angle prism ABC, both AC surface is
