The wave-particle duality, and more specifically the de Broglie interval wave, can be used to derive Heisenberg’s uncertainty principle. The Uncertainty Principle (1925-1927) This is a succinct statement of the uncertainty relation between the position and the momentum (mass times velocity) of a subatomic particle, such as an electron. Werner, Terry FarrellyThe Heisenberg uncertainty principle Δx × Δp ≥ h tells us that whenever we try to measure certain pairs of numbers we cannot get both values with high accuracy.7: $ \left ( \Delta x \right )\left ( \Delta \left [ mv \right ] \right )\geqslant \dfrac{h}{4\pi } $ Summary.
