在ripple 裏
如果增加frequence , speed 保持不變
wavelength 會縮短
那麼怎樣才能改變wave 的speed 呢?

✔ 最佳答案
Increase the water depth.Water waves propagate faster in deep water.
This knowledge is required in the CE syllabus.
Since the frequency is fixed,
wave speed increase=>wave length increase
(the wave will diffract to a greater extend while passing through a gap)

Since wave speed depends on the medium only,
the speed of a wave can be changed by medium.
the speed of a wave can be changed by medium.
