The wavelengths of the photons emitted by a potassium atom
Chapter , Problem 67(choose chapter or problem)
The wavelengths of the photons emitted by a potassium atom corresponding to transitions from the and states to the ground state are 766.41 nm and 769.90 nm. (a) Calculate the energies of the photons in electron volts. (b) The difference in the energies of the photons equals the difference in energy between the and states in potassium. Calculate (c) Estimate the magnetic field that the 4p electron in potassium experiences.
