This is something very straight-forward. de-Broglie wavelength is given by
\lambda =h/p
Where h=Planks constant
When you plot it, it resembles y=c/x graph
For p=1, \lambda =h
For p\lambda > h (For example, if p=0.5, \lambda=2h)
For p>1, \lambda<h(For example, if p=2, \lambda=0.5h)
As p tends to infinity, Wavelength tends to zero.
