在高中物理有提到 水波槽的實驗中 深水區的水波波長較長,波速較快, 淺水區是波長短,波速慢,頻率則是都相同。 想請問有人有比較直觀的解釋方法嗎 ? 為什麼深水區的波速比淺水區快 ? 如果不要從數學的角度切入 怎麼想比較好想 謝謝!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.122.141.46

呃... 水波波速正比於水深的開根號 這樣算數學嗎?XD

我知道有那個公式,不過想說有沒有比較定性的說明 = =

我猜實際上會更複雜一點,但有可能跟弦的張力類似

It's generally explained as follows:

The shallower the water, the most the water wave

senses the bottem of the water and therefore is

slowed down more..

But this reason is very vague, and don't take it
