Overview
In quantum mechanics, the de Broglie wavelength is the wavelength (位) associated with a massive particle and is related to its momentum (p) through the Planck constant (h). This concept highlights the wave-particle duality of matter.

Pro Tips
The effects of de Broglie wavelength are most significant for subatomic particles like electrons.
As velocity or mass increases, the wavelength decreases and becomes negligible for macroscopic objects.
Relativistic effects may apply as velocity approaches the speed of light (not included in this base formula).

Fun Facts
"Louis de Broglie proposed this hypothesis in 1924, which earned him the Nobel Prize in Physics."
"Electron microscopes use the wave properties of electrons (their de Broglie wavelength) to achieve much higher resolution than optical microscopes."
