The uncertinty in determining the duration during which an electron remains in a particular energy level before returning to the ground state is 2.0 x 10(^{-9})s. Calculate the uncertainty in determining its energy at that level [Take (frac{h}{2pi} = h = 1.054 times 10^{-34}) Js]
Explanation
(Delta E geq frac{h}{2pi} times frac{1}{2t} = 1.054 x 10^{-37} times frac{1}{2.0 times 10^{-9}})
(Delta E geq 5.27 times 10^{-25})J
