This interactive homework problem shows a coherent beam of photons incident on a double slit. It asks the user to duplicate the interference/diffraction pattern of photons using electrons instead. The slit width, space between slits, and distance to screen are all given in the problem. The user must determine the kinetic energy of one of the electrons. It is designed to help the student of physics understand the relationship between a particle's wavelength and momentum. The problem is accompanied by a Socratic-dialog "help" sequence designed to encourage critical thinking as users do a guided conceptual analysis before attempting the mathematics.
This item is part of a larger collection of interactive problems developed by the Illinois Physics Education Research Group.
