MEDAL IMMEDIATELY AWARDED FOR CORRECT ANSWER IN THE NEXT 15 MINUTES: Assuming that the smallest measurable wavelength in an experiment is 0.890 fm (femtometers), what is the maximum mass of an object traveling at 353 m·s–1 for which the de Broglie wavelength is observable?

Question

aaronq · Answer

the de broglie equation is $\sf \lambda=\dfrac{h}{mv}$

solve for m, $\sf m=\dfrac{h}{\lambda  v}$
