Heisenberg Equation

Postby Mary Shih 3J » Thu Oct 15, 2020 12:52 am

-In the Heisenberg questions, after finding delta p from the equation, do u always have to plug it back into delta p=mV to find uncertainty in position?

To find the uncertainty in position, once you find delta p from delta p = mv (you are given delta m and delta v in the question) you can use that to then to back track to find delta x using the equation delta p * delta x = ½ h bar.

Use the to find x because you have all the other values already.

I might have misunderstood your question, but if velocity and mass are given to you, you can solve for delta p using delta p = mass * velocity. This equation won't give you the uncertainty in position (and can only be useful if you have two of the three values needed to solve for it), but if that's what you're looking for then you would have to plug in delta p for the equation "delta x (or uncertainty in position) = h/4pi/delta p" to find the uncertainty in position.
