A modified oscilloscope is utilized to perform an electron interference experiment. Electrons are incident on a pair of narrow slits 0.0720 µm apart. The bright bands in the interference pattern are separated by 0.400 mm on a screen 24.0 cm from the slits. Decide the potential dissimilarity through which the electrons we reaccelerated to give this pattern.
