SUMMARY
The forum discussion centers on calculating the De Broglie wavelength of electrons and protons, specifically identifying the energy threshold at which non-relativistic calculations yield a 5% error. The participants highlight two approaches to the problem, with the second approach correctly utilizing relativistic principles, emphasizing that De Broglie wavelength is dependent on momentum rather than solely on kinetic energy. The consensus is that non-relativistic methods become inaccurate at higher energies, particularly for particles approaching relativistic speeds.
