摘要
从薄透镜的焦距公式出发,讨论了各种透镜在不同介质中的会聚与发散性质.透镜的会聚、发散性质既与透镜的形状和折射率有关,又与透镜两侧介质的折射率有关.
From the focal distance formula of thin lens, the convergence and divergence nature of each kind of thin lens are discussed in different media. It is related not only with its shape and the index of refraction, but also with the refractive index of media on two sidesthereof .
