Problem 13: The life time of an electron is an excited state is about 10-8 s. What is its uncertainty in energy during this time?

Solution

Given: Excited state time of the electron, Δt = 10^-8 s

Required: Uncertainty in energy, ΔE

Formula: ΔE = h/Δt , where h = 6.63 × 10^-34 J s

Put values in the formula
