摘要
研究Ｆｒａｕｎｈｏｆｅｒ′ｓ衍射装置由空气移至水或其它透明介质中衍射条纹间距的变化．在考虑到介质中光波波长会发生变化的同时，兼顾介质中透镜焦距的变化，从而进一步计算衍射条纹的间距，得出更符合事实的结论．
This paper mainly discusses the variation in the distance between two diffraction fringes when Fraunhofer′s diffraction device is moved from air to water or other transparent medium.The variation not only in light wavelength but also in the focal distance of the lens is taken into consideralion.Then we can reach the more practical facts are obtained by counting.
