The emitted light’s color and wavelength (λ) depend on the magnitude of the energy change (ΔΕ) due to the transition from one energy level to another. In your data table (see Fig. He departed from classical theory, however, by imposing a “quantum restriction” upon the condition that the electron could exist only in certain “allowed states.” The energy could have only those values given by the equation: In setting up his model, Bohr designated zero energy as the point where the proton and electron are completely separated, level infinity. Using the Bohr model equation, calculate the energy of each of the energy levels involved in the transition for each of the observed wavelengths.
