The uncertainty of the velocity (Δv) of a proton in an accelerator constitutes 0.250% of the speed of light. What is the smallest possible uncertainty in its position (Δx)? What is the uncertainty of the momentum (Δp)?
Rayleigh’s criterion is used to determine when two objects are barely resolved by a lens of diameter d. The angular separation must be greater than θR where θR = 1.22 λ/d In order to resolve two objects 4000 nm apart at a distance of 20 cm with a lens of diameter 5 cm, what energy (a) photons or (b) electrons should be used? Is this consistent with the uncertainty principle?
