Interpretation:
The minimum uncertainty in momentum and minimum uncertainty in velocity for the atomic particles like neutrons and electrons is to be determined.
Concept Introduction:
The principle that helps to locate any subatomic particle behaving as a wave is called Heisenberg’s Uncertainty Principle.
The equation of Heisenberg’s Uncertainty Principle is as:
Here,
The expression for the minimum uncertainty of momentum is as:
Here,
The relationship between meters and angstrom can be expressed as:
To convert angstromto meters, conversion factor is
The relationship between
