A certain crystalline solid can be probed using a wavelength of 0.070nm. What kinetic energy is required if the probe is
a. electrons
I dont want you to do this for me just a farken hint. I this it has something to do with
((h / .070nm)^2) / (2m) = K
h = plank's constant
m = mass of particle (in e- case its 9.1x10^-31 kg)
K = kinetic energy
I think thats how you do it but its just a guess. Im not sure how to relate K and lambda (wavelength). I dont usualy ask for homework help but this one has been kicking my ass for the past 2 hrs.
Thanks
