Heisenberg Uncertainty Principle
According to Heisenberg's uncertainty principle, which of the following statements is correct?
Select the correct option:
Solution
It is impossible to determine both position and momentum of an electron precisely
Heisenberg's Uncertainty Principle states that it is impossible to determine simultaneously the exact position and exact momentum (or velocity) of a subatomic particle like an electron. Mathematically: Δx⋅Δp≥4πh
- This is not due to instrumental limitations but is a fundamental property of matter waves.
- If uncertainty in position (Δx) is zero, then uncertainty in momentum (Δp) must be infinite, and vice versa.
