Calculate the de Broglie wavelength of a particle based on its momentum. This quantum mechanical property shows that all matter exhibits wave-like behavior, with wavelength inversely proportional to momentum.
Enter your values below
Mass of the particle
Velocity of the particle
Default: 6.626×10⁻³⁴ J·s
How this calculator works
de Broglie wavelength equals Planck's constant divided by the particle's momentum (mass times velocity).
