question 1

Multiple Choice

Uncertainty principle using ΔEΔt ≥ ħ: The energy of an electron state has an uncertainty of 0.500 eV. What is the minimum uncertainty in the lifetime of the level? (ħ = 1.055 × 10^-34 J ∙ s = 6.591 × 10^-16 eV ∙ s, 1 eV = 1.60 × 10^-19 J)

• A) 1.32 × 10^{-15 s}
• B) 8.28 × 10^{-15 s}
• C) 1.32 × 10^{-11 s}
• D) 8.28 × 10^{-11 s}
• E) 1.32 × 10^{-8 s}
