You are conducting experiments with your x-ray diffractometer.
(a) A specimen of molybdenum is exposed to a beam of monochromatic x-rays of wavelength set by the Kα line of silver. Calculate the value of the smallest Bragg angle, θhkl, at which you can expect to observe reflections from the molybdenum specimen.
λKα of Mo = 0.721 Å
lattice constant of Mo, a = 3.15 Å
λKα of Ag = 0.561 Å
lattice constant of Ag, a = 4.09 Å
(b) If you wish to repeat the experiment described in part (a) but using an electron diffractometer, across what vale of potential difference must electrons be accelerated from rest in order to give the identical value for the smallest Bragg angle, θhkl?
hi, I'm one of the community TA for 3.091x. Please stop cheating, it's quite silly.

Odesa, why are you helping people to cheat?
how do I believe you?
please odesa tell me because they are not suppose to be here if they know it all
Odesa, like to help each other to cheat because he/she like to be cheated... Hahaha
