Uncertainty principle using ΔEΔt ≥ ħ/2: The excited state of a certain atom is 3.2 eV ±0.21 eV. ( ħ = 1.055 × 10-34 J ∙ s = 6.591 × 10-16 eV ∙ s, 1 eV = 1.60 × 10-19 J)
(a) What is the average lifetime of this state?
(b) If the excited energy were doubled to 6.4 eV ± 0.21 eV, how would the lifetime be affected?
