Reference no: EM13487039

Electrons are accelerated by a potential and directed upon a thin salt crystal that has inter-atomic spacing of 0.282 cm. The diffraction pattern of electrons on a CRT screen located 50.0 cm away shows a peak 3.0 mm on either side of the central peak. What was the acceleration potential? (Hint: The electrons are behaving like a wave.)
