Practice question · Select all that apply
Select every statement that correctly describes the uncertainty principle.
Hints
- Two options describe the same misconception in different words.
- The principle is about what values a particle can HAVE, not about what we can measure.
Show the answer
- A. It concerns position and momentum held simultaneously
- B. It is a fundamental limit of nature, not a limitation of equipment
- E. The more precisely position is known, the less precisely momentum can be
Why
The principle says position and momentum cannot both have precise values at once, it is a statement about nature, not about laboratory technique. Options 1 and 4 are the 'clumsy measurement' misreading; no improvement in instruments could ever evade the limit.
