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.

Quantum
Photon Energy Calculator
Compute the energy of a single photon from its wavelength using E = hc/λ, the Planck-Einstein relation. Returns energy in joules; convert to electron-volts by dividing by 1.602 × 10⁻¹⁹.
