下面介绍一种简易牛顿七色盘的制作方法,供参考.取一块薄金属板,剪成一直径为5厘米左右的圆板.在圆板上打两个相距1厘米左右的小孔,孔的中心位置以圆板的圆心为对称中心,如图1所示.在该圆板上涂上红、绿、兰三种颜色,如图2所示.然后取一根长约1米左右轻质 The following describes a simple Newton seven-color disk production method, for reference. Take a thin metal plate, cut into a circular plate with a diameter of about 5 cm. In the circular plate hit two holes about 1 cm apart, the center of the hole The position is centered on the center of the circular plate, as shown in Fig. 1. The plate is painted with red, green, and blue colors, as shown in Figure 2. Then a light weight of about 1 meter is taken.
