Suppose that at a certain time a quanton has a well-defined position x = 0.15 nm. At that time, we perform an experiment to determine the quanton’s momentum, and find it has a value that corresponds to a de Broglie wavelength of 0.45 nm to a high degree of precision. What can we say about the quanton’s position after the experiment?
A. It is still 0.15 nm.
B. It is now 0.45 nm.
C. It is now within ±0.45 nm of 0.15 nm.
D. It is now undefined but probably close to 0.15 nm.
E. It is now completely undefined.
F. Other (specify).
D. It is now undefined but probably close to 0.15 nm.
