How does wavelength change with speed?

I thought I heard the fact that when you make a particle faster it's wavelength get's bigger, and if we accellerate a baseball enough it's wavelength goes visible? but is that just a misunderstanding and opposite... because one can see in the broglie wavelength equation:

λ = h/mv that obviously as v(velocity/speed) increases... the wavelenght becomes smaller... right? wasn't it all just a misunderstanding on my half?

UH ... what is the wavelength of a baseball?

Yes, the de Broglie wavelength gets shorter as the particles momentum increases.

ah just wanted to make sure, thanks
