How did electrons emit light according to the Bohr model?
According to the Bohr model, electrons exist only in specific, allowed orbits around the nucleus, each corresponding to a distinct energy level.12
Electrons emit light when they undergo a transition from an outer, higher-energy orbit to an inner, lower-energy orbit. Because these orbits have fixed energy values, the electron loses a precise amount of energy during this abrupt transition. This lost energy is released as a bundle of electromagnetic radiation known as a photon.312
The energy of the emitted photonâand consequently the frequency of the lightâis determined by the difference in energy between the two orbits. This process, often described as a quantum leap or jump, explains why atoms emit light at specific, characteristic wavelengths rather than a continuous spectrum.123
