QUESTION

# 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"
