摘要
介绍了薄透镜焦距测定中观察到的一种反射成像现象,指出利用薄透镜正反两次反射成像可较好地测定其折射率和前后表面的曲率半径。
This article introduces a reflective imaging phenomenon observed in the measurement of thin-lens focal length. It points out that the thin-lens's refractive index and curvature radius of its back and front surface could be well measured by two reflective imaging of its con and front side.
