顾名思义,望远镜能让我们看清远处的事物。那么它的工作原理是什么呢?结合下面这幅图片,你能更好地理解本文。参考译文:为了理解普通的望远镜是如何让很远的东西看起来很近,不妨思考一下我们为什么不能用肉眼看见远处的事物吧。首先,瞳孔无法接收足够的光线让远处的事物的细节变得清晰。再说,一个远处的物体只能在眼球背面投射出一小幅图像。
As the name suggests, the telescope allows us to see things in the distance. So what does it do? With this picture below, you can understand this article better. In order to understand how ordinary telescopes can make very distant things look close, consider why we can not see things far away with the naked eye. First of all, the pupil can not receive enough light to make the details of the distant things clear. Besides, a distant object can only project a small image on the back of the eyeball.
