What is the speed of a 796eV electron?
E = hc/lambda
E = hv
The Attempt at a Solution
I'm not sure how to get a value for meters... I know if I take h (plank's constant) and divide the electron, I will get 4.14E-15 ev*s / 796 eV = 5.20E-18 seconds, but that is just a time, i don't know how to get the distance for that time...
