Dear Friends,

HUP says that dx*dp>=h.Is it also true from frame of refrence of electron, at that time I know position and Momemtum of electron ?

Dear Friends,

I want to ask to Profssionals that, HUP says that dx*dp>=h.

Is it also true from the frame of refrence of Electron, because at that time I know the position and momemtum of elecron?

Are you asking if the electron "knows" its position and momentum better than the HUP?

because at that time I know the position and momemtum of elecron?

that's impossible to judge according to the heisenberg uncertainty principle.

Frames of refrences are concepts of classical mechanics and applied to particles or rigid bodies whose location can be exactly determined.

In this case it is impossible to do so because we have a matter wave not a particle.

I got the answer to that question,

The frame of refrence of that electron is as uncertain as that electron.

Hi budullewraagh,

How can I solve Newton's laws of motion using laws of QM?

I have to solve TDSE ( Time dependent Shrodinger's Eq) right.

Let us a problem of stone fall under gravity.

Then V = mgh

how to find Psi(h,t) ?

Assuming your floor is your potential step V0.

 

Then solve your time-indepedent Schrodinder wave equation (Use time-indedent version since we are not interested in the effect of dynamical disturbance of the system).

(-hbar2/2m)*d2Psi/dx2 + V(x)Psi(x) = E(x)Psi(x)

 

Similar to the electron incident on the potential step. Solve it in the same way.
