de broglie wavelength

[Garvit Goel]

i was working on atomic structure and i stuck here.
how can a wave be associated to any material? is it related to wavelength of colur it emits or is it the wavelength of vibrations after it has been stuck by something???
what is it??

Material's have wave-like and particle like behavior.
The de Broglie wavelength is the characteristic wavelength of the material's wavefunction.
