de Broglie Wavelength Calculator
Calculate the wavelength associated with moving particles according to wave-particle duality.
Electron: 9.109e-31 kg, Proton: 1.673e-27 kg
Results
de Broglie Wavelength (λ): 7.2742e-10 m
de Broglie Wavelength: 7.2742 Å
Momentum (p): 9.1090e-25 kg·m/s
Kinetic Energy: 4.5545e-19 J
Kinetic Energy: 2.8430 eV
Formulas
de Broglie wavelength: λ = h/p = h/(mv)
From kinetic energy: λ = h/√(2mE)
Thermal wavelength: λ_th = h/√(2πmk_B T)
h = 6.626 × 10⁻³⁴ J·s
