✔ 最佳答案
哈哈哈哈哈 .我前幾日做呢條都有同你一樣既問題就等我幫你LA
其實我EASY 佢條問題, 係問你 particle l
係particle l particle l particle l particle l particle l
既s/t graph 唔係成個graph! 如果佢問你成個graph
ans就係 C 但係而家係問你 particle l particle l particle l particle l
SO? 解答到你問題?
參考: 前幾日我仲一口咬定呢條ANS錯左...

上面果二個人都亂黎既~
因為依個係longitudinal wave~佢每3個picticle就變成密~係picticlee 密的三個是def~咁當下一秒向right移的時候~g就會移去密的那邊~相對地~hij只會移去left 佢話right係正~所以i個s/t就係由負去正
