Electrons

Can an electron be at rest?

[vincentchan]

yes, according the uncertainty principle, \Delta x \Delta p \geq h/4 \pi , when you completely have no idea where the electron is... it could be at rest......(it's like playing HIDE AND SEEK when you were young)

Ahhh, so that is what is meant when the de broglie wavelenght is infinite? h/0

[vincentchan]

yes, p = hk/2\pi = h/ \lambda
if the uncertainty of momentum is zero, sure the wavelength will go to infinity. That's also mean you have completely no idea where the electron is.....
