通过实验可以探究凸透镜成像的规律,通过作图可以帮助我们进一步理解凸透镜成像的规律.通过凸透镜光心的光线传播方向不改变;跟主光轴平行的光线,通过凸透镜后过焦点;过焦点的光线通过凸透镜后跟主光轴平行射出.
Through the experiment can explore the law of convex lens imaging, through the mapping can help us to further understand the law of convex lens imaging through the convex lens optical center of the light propagation direction does not change; with the main optical axis parallel to the light through the lens after the focus; Light through the convex lens followed by the main optical axis parallel injection.
