The Heisenberg Uncertainty principle states that ΔxΔp > h/4π. What is represented by the terms Δx, and Δp? What can we say about p if the precise value of x is known? What does this mean for experimental results.

  1. Δx and Δp represent the uncertainty in position and the uncertainty in momentum respectively.
  2. If x is known absolutely then p cannot be known at all.
  3. This means that the precise position and momentum of a particle cannot be known at the same time.
