“波的干涉”是高一物理教学的一个难点,也是教学研究中常常受到关注的一个课题。这里从重点中学学生的基础出发,加强实验,增大容量,作了如下的探索。波是振动在媒质中的传播,波动中各质点的位移既是空间的函数,又是时间的函数,而两列波在媒质中相遇叠加,就更具有复杂性。过去在教学上往往先讲波的叠加原理,再详细分析如附图所示的两列同频率同相位的水面波相遇时,在某一时刻波峰与波峰相遇的各点,波谷与波谷相遇的各点都在α线上(该处振动加强) “The interference of waves” is a difficult point in the physics teaching of higher grades, and it is also a subject that often attracts attention in teaching and research. Here, from the basis of the key middle school students, to strengthen experiments and increase capacity, the following explorations were made. Wave is the propagation of vibration in media. The displacement of each particle in a wave is not only a function of space but also a function of time. The two waves of waves meet and accumulate in the medium, which is more complex. In the past, the principle of wave superposition was often first discussed. Then, when two water waves with the same frequency and phase were encountered as shown in the figure, the points where the peaks and crests meet at a certain time, and the troughs and troughs met each other. All points are on the α line (where the vibration is strengthened)
