Calculate the wavelength of electrons traveling at 1.15x10^5 m/s
λ = h/m*v
The Attempt at a Solution
I converted J*s to SI units (kg⋅m2⋅s−2) and then substituted out all known values, to get:
λ = (6.626x10^-34 kg⋅m2⋅s−2)/(9.11x10^-31kg)(1.15x10^5 m/s)
After canceling out like units and doing the math, I get:
λ = 6.00x10^-9m
The text gives the solution as 6.33nm. I can't figure out how they got there (and why they converted to nm?).
Is this an error in the text or (more likely) in my logic/calcuations?
Any/all input is appreciated. Thanks!
