## anonymous 3 years ago Assuming that the smallest measurable wavelength in an experiment is 0.610 fm (femtometers), what is the maximum mass of an object traveling at 199 m·s–1 for which the de Broglie wavelength is observable?

use the deBroglie equation $\lambda=\frac{ h }{ mv }$

just be sure to convert your units properly first
