1. The problem statement, all variables and given/known data Suppose you measured the x-component of position of an electron to an accuracy matching it’s de Broglie wavelength, i.e., Δx = lambda/2. What is the relative uncertainty in the electron’s x-component of momentum, Δp/p? 2. Relevant equations ΔxΔp >= h(bar)/2 3. The attempt at a solution I just wanted to clarify that relative uncertainty is Δp, not Δp/p. My professor writes these questions and is currently sick, so I feel like he may have not been thinking completely clearly... I am finding Δp, and not the ratio Δp/p? I am pretty sure I merely need Δp.
