@Neila
Where does your initial equation for the speed of the probability wave come from?

Talking

@Woody:
It's from Duck de Brogile, the ancestor of probability (matter) wave...

Just a stray thought that might have some bearing on what you are asking. Waves have two speeds: group and phase speed. The group speed is $\displaystyle v_g = \dfrac{d \omega }{dk}$ and is what you would say is the speed of the wave. The phase speed is $\displaystyle v_p = \dfrac{ \omega }{k}$ and can be faster or slower than the group speed.

A light wave has $\displaystyle v_g = c$, whereas the phase speed can actually be faster than this.

Red face simple vs complicated

@dragon:
Why must you talk about group speed? Can you use simplified method to explore physical principle and highlight the emphasis?

By the way, it is "Duc" (French for "Duke) de Broglie

I mentioned it because, honestly, I still don't know what you are asking in that last post! I was taking a guess that what I said might be relevent.

Talking relevant

@no one:
I would rather talk about the ancient Chinese fiction Travelling to the West again...
Monk Pig (猪八戒) always considered that the beautys were relevant to himself...
The master as well as the captain Monk Tang (唐僧) simplified the world and considered that only the Buddism was relevant to himself...and he got the "trueth".
