开栏的话近年来,中招考试增加了实验操作考试.为了帮助同学们更好地进行物理实验操作,我刊将刊发一系列物理实验考试中的实验操作文章,希望对提高同学们的实验操作能力有所帮助.探究振动产生的声音实验器材:一个音叉、固定音叉的底座、音叉槌、粘在细绳上的乒乓球.实验要求:选择合适的器材,观察发声的物体是否在振动,观察当物体停止振动时是否还能发声.过程与记录:(1)将音叉固定在底座上.
In recent years, the middle school entrance examination increased the experimental operation test.In order to help students better physical experiment operation, I published a series of experimental articles in the physical experiment test operation, I hope to improve the students experiment Operational ability to help. To explore the sound of vibration Experimental equipment: a tuning fork, the base of the fixed tuning fork, fork and hammer, stick to the string on the table tennis. Experimental requirements: Select the appropriate equipment to observe the sound object is vibrating, Observe whether the object can vibrate when it stops vibrating Process and record: (1) Fix the tuning fork on the base.
