Heisenberg Uncertainty Principle - Practice Questions & MCQ

Heisenberg’s uncertainty principle:

It states that it is impossible to determine simultaneously, the exact position and exact momentum (or velocity) of an electron.

If an attempt is made to ensure that any one of these two quantities are measured with a higher accuracy, then the other quantity becomes less accurate.

Mathematically, the product of uncertainty in position(Δx) and uncertainty in momentum(ΔP) is equal to or greater than h/4π

$\Delta x . \Delta P \geq \frac{h}{4 \pi}$

It can be proved mathematically that the uncertainty principle is only significant to subatomic particles but not insignificant for everyday large sized objects.
