我問點解transver wave 一定要o係水面進行....水底唔可以有....
同埋水底d野move的話..e.g. 游緊既魚....算唔算都produce緊d longitudinal wave....
physics...transver wave同longitudinal wave...

✔ 最佳答案
相信你係指海浪 as transverse wave，海浪係同水面張力有關，所以只有在水面才可以有。理論上沒有禁止水底有transverse wave 出現，只要可以拎水分子好似海浪咁郁就得，問題係點樣可以拎到佢地咁郁。
魚游動擺尾只可以令到水流動，但不會拎到水分子而 longitudinal wave 的分式擺動。同上，理論上沒有禁止水底不能有longitudinal wave，問題係點拎到水分子按longitudinal wave 的分式運動。
要留心 wave 的存在，是同媒介有關，如繩、電磁場等。與振動源關係不大。

Both transverse wave and lognitudinal wave can be produced and propagated under water.
Regarding the fish, unless the fish could vibrate in a very regular manner (fixed frequency), otherwise the agitation it caused cannot be regarded as wave.
