用笔型激光演示衍射现象,精度高、使用方便,但亮度低,教室上课演示效果较差.我们制作的多缝衍射演示器演示操作简单,衍射效果非常好.经过认真实验,共同制成的仪器形状及用照相机拍摄的效果图.(本实验获浙江省金华市2006年物理实验比赛一等奖、浙江省2006物理实验比赛一等奖)为 Diffraction with a pen laser demonstrates the diffraction phenomenon, high precision, easy to use, but the brightness is low, the demonstration of the classroom class is poor. The multi-slit diffraction demonstrator we produced demonstrated simple operation, diffraction effect is very good. After careful experiments, made together The shape of the instrument and the effect picture taken with a camera. (This experiment was awarded the first prize of the 2006 physical experiment competition in Jinhua City, Zhejiang Province, and the first prize of the 2006 Physical Experiment Competition in Zhejiang Province).
