How Does the Uncertainty Principle Affect Momentum Measurement Accuracy?

Click For Summary
SUMMARY

The discussion centers on the Heisenberg Uncertainty Principle, which asserts that it is fundamentally impossible to simultaneously measure both the position and momentum of a particle, such as an electron, with arbitrary precision. Specifically, if the position of an electron is measured to within 1 angstrom (1 x 10-10 meters), the uncertainty in its momentum becomes significant, leading to a quantifiable limit on measurement accuracy. This principle is critical in quantum mechanics and highlights the intrinsic limitations of measurement at the quantum level.

Homework Statement



Suppose you want to measure the position of an electron to within 1 angstrom. If you also want to measure its momentum, how accurately can you do this if you don't want to mess up your measurement of its position?

Homework Equations



An angstrom is 1 x 10-10


The Attempt at a Solution


Well the principle states that it's impossible to know both the position and momentum of a particle at the same time. My question is to what degree of accuracy can I measure the position of the electron?
