WebThe energy difference between the various levels of Bohr's model and the wavelengths of absorbed or emitted photons is represented by the Rydberg formula. It can be stated mathematically as-. 1/λ = RZ 2 (1/n 12 − 1/n 2h) Where, λ is the wavelength. R is the Rydberg constant which has a value of 1.09737107 m -1. WebThe Bohr radius is a physical constant that is equal to the distance between the nucleus and the electron of a hydrogen atom in the ground state. Its value is given by the …
