One of the most compelling demonstrations of wave-particle dual- ity is the wave-like interference pattern displayed by electrons (which otherwise behave like a particle) when passing through a pair of double slits. If a beam of electrons is created by accelerating them from rest through a potential difference of just 500 V, and this beam is trained on a pair of slits 10 µm apart with a detector 1 m behind the slits, what is the separa- tion between adjacent bright spots on the 38.23 screen?
