The de Broglie wavelength:

$\overline{){\mathbf{\lambda }}{\mathbf{=}}\frac{\mathbf{h}}{\mathbf{p}}}$, where h is Plank's constant and p is the momentum of the particle.

For the purposes of precise explanation, let's consider a baseball of a mass of 0.2kg that moves with a speed of 15 m/s.

The de Broglie wavelength of such a ball is in the order of 10-34 m.
