一、仪器装置介绍:图中A是固定在铁架上可以转动的平面镜,专为将太阳光反射到教室内用的。B是固定在高铁架上可以转动的平面镜,镜面用中间留有窄缝的黑纸糊起来,专供反射入射线用。C是供实验用的玻璃槽,高33厘米,宽35厘米,阔11厘米,槽的一面用黑纸糊起来,另一面在它的正中用白洋漆划一条较粗的法线。二、这种装置的优点:这些验证光的折射仪器都很简单,可以在一般没有电源的县城及乡村学校采用。
First, the installation of equipment Description: Figure A is fixed on the iron frame can rotate the plane mirror, designed to reflect the sun to the classroom. B is fixed on the high-speed rail can rotate the plane mirror, the mirror with a narrow gap between the left black paper paste, specifically for reflection into the ray. C is a glass tank for experimental use. It is 33 cm high, 35 cm wide and 11 cm wide. One side of the tank is covered with black paper and the other side is given a thicker normal using a white foreign paint. Second, the advantages of this device: The verification of light refraction instruments are very simple, can be used in the county and rural schools generally do not have power.
