An electron in the state of hydrogen remains there on
Chapter 28, Problem 46(choose chapter or problem)
An electron in the n = 2 state of hydrogen remains there on average about \(10^{-8}\ s\) before jumping to the n = 1 state. (a) Estimate the uncertainty in the energy of the n = 2 state. (b) What fraction of the transition energy is this? (c)What is the wavelength, and width (in nm), of this line in the spectrum of hydrogen?
