How Is Uncertainty in Position Determined for a Confined Proton?

MarkusNaslund19 · Apr 11, 2007

Let's say a proton is confined to some diameter, d. What would be the uncertainty in the position?

In some questions they use delx as (1/2)d as the uncertainty in position. In other cases they use the entire d as the uncertainty. This is extremely confusing...

Must be d/2

If I guess that the proton is in the middle, then the most I can be wrong by is d/2.
