A bubble chamber forms an image of a particle's trajectory as a series of bubbles on a photographic plate. Momentum and energy can be determined from the trajectory, but quantum mechanics and experimental uncertainty place limits on how accurately momentum and energy can be determined. (a) The width of a bubble limits the resolution of a particle's position. If a particle's track is 1 μm wide, what is the minimum uncertainty in its momentum? (b) There is some uncertainty in the time that elapses as a particle crosses the bubble chamber. If the uncertainty in a particle's time of flight is 1 ns, what is the minimum uncertainty in its energy?
