# What is the wavelength of an electron (mass = 9.109 ×10-28 g) that is traveling 6.50 × 103 m/s?

The wavelength ##lambda=1.12xx10^(-7)"m"##

##lambda=(h)/(mv)##

##h## = Planck's Constant = ##6.636xx10^(-34)"J.s"##

##m## = mass

##v## = velocity

##lambda=(6.636xx10^(-34))/(9.109xx10^(-31)xx6.50xx10^(3))"m"##

##lambda=1.12xx10^(-7)"m"##
