### DeBroglie Wavelength

Why does the wavelength matter in terms of seeing H atoms traveling in a wavelike motion?

Hi Divya!

de Broglie's wavelength formula was designed to be a generalized extension of Einstein's Wave-Particle Duality of Light. When this formula is applied to particles with small masses, we can see that its relatively significant values show that small particles have large wavelengths relative to their sizes. The wavelength itself PROVES that hydrogen atoms, electrons, or anything else all have wavelike properties. If something acts as a wave, it'll have a frequency and a wavelength, right? So de Broglie's equation just proves that anything can express wavelike properties, not just light/photons.

Hope this helps!
