Explanation:
The <u>Heisenberg uncertainty principle</u> postulates that the fact each particle has a wave associated with it, imposes restrictions on the ability to determine its position and speed at the same time.
In other words:
It is impossible to measure simultaneously (according to quantum physics), and with absolute precision, the value of the position and the momentum (linear momentum) of a particle. Thus, in general, the greater the precision in the measurement of one of these magnitudes, the greater the uncertainty in the measure of the other complementary variable.
Mathematically this principle is written as:
(1)
Where:
is the uncertainty in the position of the electron
is the Planck constant
is the mass of the electron
is the uncertainty in the velocity of the electron.
If we know the accuracy of the velocity is of the velocity of the electron
, then
is:
(2)
Now, the least possible uncertainty in position is:
(3)
(4)
Finally:
