1. The problem statement, all variables and given/known data Calculate the wavelength of electrons traveling at 1.15x10^5 m/s 2. Relevant equations λ = h/m*v Given values: h=6.626x10^-34 J*s m=9.11x10^-31kg v=1.15x10^5 m/s 3. 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!
