Formula and explanation
Formula: Δ x · Δ p ≥ (h)/(4π), where Δ x is the uncertainty in position, Δ p is the uncertainty in momentum, and h is Planck's constant. Applicable Conditions: Microscopic particles (e.g., electrons). Brief Explanation: This principle states that it is impossible to simultaneously determine the exact position and momentum of a microscopic particle. The more precisely the position is known, the less precisely the momentum is known, and vice versa. It is a fundamental principle of quantum mechanics.
