Electron interference patterns are made with shooting electrons with 50 keV of kinetic energy during two slits spaced 1.0 micro m apart. The fringes were recorded on a detector 1.0m behind the slits.
What was the speed of the electrons? (The speed is large sufficient to justify using relativity, however for simplicity do this as anon realistic calculation.
What was the actual spacing on the detector among adjacent bright fringes?
