Uncertainty Principle Hard
Heisenberg uncertainty principle states product of position and momentum uncertainties is at least:
Select the correct option:
Solution
ħ/2
The Heisenberg Uncertainty Principle states that there is a fundamental limit to how precisely we can simultaneously know certain pairs of physical properties (conjugate variables). Δx⋅Δp≥2ℏ where ℏ=2πh is the reduced Planck constant. This is not a limit of measurement tools, but a fundamental property of wave-like systems.
