Quantum
De Broglie Wavelength Calculator
Compute the de Broglie wavelength λ = h/(m·v) of a massive particle from its mass and velocity. Demonstrates wave-particle duality: every massive particle has an associated quantum wavelength.
Fill in the required fields to see your result.
Quantum
Heisenberg Uncertainty Principle Calculator
Compute the minimum momentum uncertainty Δp ≥ h/(4π·Δx) implied by Heisenberg's uncertainty principle for a given position uncertainty. The result is the lower bound on simultaneously measurable momentum spread.
