alleryHeisenberg's uncertainty principle is most accurately stated as:
A$\Delta x \cdot \Delta p = 0$ (perfect precision)
B$\Delta x + \Delta p < h/2$ (sum bound)
C$\Delta x \cdot \Delta p \geq h/(4\pi)$ (product bound)
D$\Delta x = \Delta p$ (equal uncertainties)
Answer & Solution
Correct answer: C. $\Delta x \cdot \Delta p \geq h/(4\pi)$ (product bound)
**Heisenberg:** Δx × Δp ≥ h/(4π).
Product of position and momentum uncertainties has a MINIMUM.
So we cannot know both with arbitrary precision.
Crucial for quantum mechanics.
