SUMMARY
The discussion centers on calculating the de Broglie wavelength of a proton accelerated from rest through a potential of 1 kV. The correct formula to use is λ = h/p, where h is the Planck constant and p is the momentum of the proton. The user initially miscalculated the momentum due to unit confusion, using electron volts instead of joules. The correct velocity of the proton after acceleration is approximately 437,621.13 m/s, leading to an accurate calculation of the de Broglie wavelength.
