Uncertainty in measuring speed of a particle is numerically equal to uncertainty in measuring its po — Atomic Structure Chemistry Question
Question
Uncertainty in measuring speed of a particle is numerically equal to uncertainty in measuring its position. The value of these uncertainties will be
Answer: D
💡 Solution & Explanation
If Δx = Δv, then (Δv)^2 * m ≥ h/(4π) => Δv ≥ √(h/(4π*m)). So uncertainties can be equal to or greater than √(h/(4π*m)).
