摘要: 折射率是重要的光学参量之一. 作者应用偏振光实验仪( WPZ 型) 台架和光源,用直径为6 cm、200 ml 玻璃烧杯内 正中用60 mm × 80 mm × 2 mm 矩形的透明玻璃片分隔为两半,设计一种新的简单实验容器,根据光的全反射定律测定任意透 明液体的折射率. 并用此方法测定蒸馏水、饱和蔗糖和二碘甲烷的折射率. 实验表明该方法有便于操作、成本低、效率较高等 优点,对透明液体的折射率测量具有一定的参考价值.

Abstract: Refractive index is one of the important optical parameters. A new simple experimental instrument is designed by using polarized light experimental instrument ( WPZ type) stand,light source,and a diameter of 6 cm 200 ml glass beaker which of 60 × 80 × 2 ( mm3 ) rectangular transparent glass is in the middle,madding it be separated into the two parts. The refractive index of any kind of transparent liquid is measured according to the total reflection law of light. And the refractive index of distilled water,saturated sucrose and diiodomethane was measured by this method. The experimental results show that this method has the advantages of easy operation,low cost and high efficiency,and has certain reference value for the measurement of refractive index of transparent liquid.
