## De Broglie Wavelength
All matter has wave-like properties. The de Broglie wavelength describes the wave nature of particles.
### Formula
**lambda = h / (m * v) = h / p**
where h = 6.626 x 10^-34 J·s is Planck's constant and p = mv is the momentum. Heavier or faster particles have shorter wavelengths.

Exemple Résolu
An electron (m = 9.109e-31 kg) traveling at 1e6 m/s.
- lambda = h / (m*v)
- lambda = 6.626e-34 / (9.109e-31 * 1e6)
- lambda = 6.626e-34 / 9.109e-25
- lambda = 7.274e-10 m = 0.7274 nm
