“利用双缝干涉测定光波的波长”分组实验中,学生对干涉仪结构不熟悉,调节困难,很费时。我们摸索出下面方法,教师在1—3分钟,学生在5—10分钟内,可迅速调出干涉条纹。 1.粗调:装置如图所示,调节光学系统等高共轴,使光轴和光具座导轨平行。先不安装滤光片,让光通过单缝照于双缝上形成一条亮带。松开止动螺丝⑦,取下旋转测量显微镜①,用眼直看。左右调节旋扭③,使通过双缝的光线不照射筒壁,处于简的正中。
“The use of double-slit interference wavelength of light” group experiment, the students are not familiar with the structure of the interferometer, the adjustment difficult, it is time-consuming. We explored the following methods, teachers in 1-3 minutes, students in 5-10 minutes, can quickly bring out the interference fringes. 1. Coarse adjustment: As shown in the figure, adjust the optical system and other high coaxial, so that the optical axis and optical bench rail parallel. Do not install the filter, let the light through a single slit in the double slit to form a bright band. Loosen the stop screw ⑦, remove the rotation measuring microscope ①, look straight with the eyes. Left and right adjustment knob ③, so that the light through the double slit does not illuminate the tube wall, in Jane's middle.
