想問吓點解當兩個wave（一左一右，一峰一谷，equal ampltitude）meet完之後，會保持原本既形狀離開，好似大家冇見過面咁。
乜唔係撞完後就energy抵銷哂，之後就停哂咩？
superposition疊加原理

✔ 最佳答案
The energy of the two waves would not be "cancelled". If this happened, the Law of Conservation of Energy would be violated.Take waves on an elastic string for exmaple, when the two waves meet, the energy is temporarily stored in the elastic string as potential energy. Such energy will be restoring to the two waves after they separate.

If It Is Constructive Interference,Two Pulse Meets,They Will Produces A New Amplitude,This Amplitude Is Biger Than The Two Pulse.
For Destructive Interference,Two Pulse Meets,They Will Produces A New Amplitude,This Amplitude Is Smaller Than The Two Pulse,
But They Will Cancelled After They Meet,
