# De Broglie wavelength

If, in the expression for the de Broglie wavelength, we let m -> infinity, do we get the classical result for matter?

de Broglie wavelength = h/mv

so as m goes to infinity the de Broglie wavelength goes to 0. So does this mean that particles with larger mass don't display wavelike properties and therefore can be treated as a point particle which means we can apply classical Newtonian physics?

The de Broglie wavelength assumes that ALL particles exist as a wave with wavelength h/mv

Yeah I understand that but if their wavelength is small enough they don't display (a cricket ball doesn't display wave like properties) wave like properties?
