Module Post-Assessment

Postby KMcFarland_2L » Mon Oct 12, 2020 2:35 pm

How does the precision of the position affect the precision of the momentum, and vice versa? For example, if the position determined is more precise, will that make the momentum determined less precise or more precise?

If the position determined is more precise, then the momentum determined will be less precise. If the momentum determined is more precise, then the position determined will be less precise. This is due to the Heisenberg Uncertainty Principle: the product of the uncertainty in position and the uncertainty in momentum must be greater than or equal to h/(4*pi). Therefore, if the uncertainty in position decreases, then the uncertainty in momentum must increase in order to meet the condition. I hope this helps!
