WebThis is an extremely useful equation, so usually you see this called the Balmer-Rydberg equation. We've derived this equation using the assumptions of the Bohr model, and this equation is extremely useful because it explains the entire emission spectrum of hydrogen. This is again, this is why we were exploring the Bohr model in the first place. WebSolution. We can use de Broglie’s equation to solve this problem, but we first must do a unit conversion of Planck’s constant. You learned earlier that 1 J = 1 kg m 2 /s 2. Thus, we can write h = 6.626 × 10 –34 J s as 6.626 × 10 –34 kg m 2 /s. λ = h m v.

WebPostulates of the Bohr Model: 1) Electrons move in specific circular orbits only. 2) As an atom absorbs energy, the electron jumps to a larger orbit, of higher energy (an excited state). 3) As an atom emits energy, it “falls” to a smaller, lower energy orbit. http://alpha.chem.umb.edu/chemistry/ch115/carter/files/103more/BohrEquations.pdf
