Explain Werner Heisenberg's uncertainty ...

Explain Werner Heisenberg's uncertainty principle (qualitative).

Text Solution

Verified by Experts

It is impossible to determine both the momentum (particle nature) and position (wave nature) of a moving sub atomic particle simultaneously with absolute accuracy.
Mathematically `Delta`x`xx` `Deltap = h // 4pi` where `Deltax` = uncertainty in position:
`Deltap`= uncertainty in momentum , h = Plank's constant`= 6.626xx 10^(-34)` Js.
