Q
Q: What is the uncertainty principle formulated by Heisenberg?
Solution:
The uncertainty principle states that the product of the uncertainties in position (Δx) and momentum (Δp) is greater than or equal to ħ/2.
Steps: 7
Show Steps
Step 1: Understand that the uncertainty principle is a concept in quantum mechanics.
Step 2: Know that it was formulated by a scientist named Werner Heisenberg.
Step 3: Recognize that the principle deals with two important properties of particles: position and momentum.
Step 4: Position refers to where a particle is located, and momentum refers to how fast it is moving and in what direction.
Step 5: The principle states that you cannot know both the exact position and the exact momentum of a particle at the same time.
Step 6: The more accurately you know the position (Δx), the less accurately you can know the momentum (Δp), and vice versa.
Step 7: The relationship between these uncertainties is expressed mathematically: Δx * Δp ≥ ħ/2, where ħ (h-bar) is a constant.
