I have a relatively simple question. I should know this, but...(adsbygoogle = window.adsbygoogle || []).push({});

I need to solve for the deBroglie wavelength when only the kinetic energy is known. Shouldn't I be able to convert kE to momentum (p), when the object does not have a known velocity or mass...?

Much thanks...
