SUMMARY
The discussion centers on calculating the minimum uncertainty in the speed of a particle using the Heisenberg Uncertainty Principle and de Broglie wavelength. Given an average speed of 4.7 x 105 m/s, the uncertainty in position is set equal to the de Broglie wavelength. By applying the equations Δp * Δy = h/(4π) and λ = h/p, the solution derives that the minimum uncertainty in speed (Δv) is calculated as Δv = v/(4π), leading to a definitive understanding of the relationship between momentum and uncertainty.
