Question

State Heinsenberg's uncertainty principle?

Answer 1

Heisenberg's uncertainty principle:
It is not possible to determine simultaneously the position and momentum of a moving microscopic particle (electron) with absolute accuracy.
$\Delta X\Delta P>\frac{h}{4\pi }$
$\Delta X\Delta V>\frac{h}{4\pi m}$
$\Delta X=$ uncertainty in the determination of position
$\Delta P=$ uncertainty in the determination of momentum
$\Delta V=$ uncertainty in the determination of velocity
