ASK YOUR TEACHER PRACTICE ANOTHER A modified oscilloscope is used to perform an electron interference experiment. Electrons are incident on a pair of narrow slits 0.041 0 pm apart. The bright bands in the interference pattern are separated by 0.400 mm on a screen 22.5 cm from the slits. Determine the potential difference through which the electrons were accelerated to give this pattern. [ V Need Help? [[Reaa ] [ watehw ] Submit
