Final answer:
Bohr's model of the atom explains that emission spectra are produced when electrons in the atom move between energy levels, releasing energy in the form of light. The energy emitted corresponds to the difference in energy levels, resulting in specific wavelengths of light observed in an emission spectrum.
Step-by-step explanation:
According to Bohr's model of the atom, emission spectra are produced when electrons in the atom move between energy levels. In this model, electrons occupy specific orbitals with specific amounts of energy. When an electron absorbs energy and jumps to a higher energy level, it is in an excited state.
As the electron returns to a lower energy level, it releases the absorbed energy in the form of light, called a photon. The energy emitted is precise and corresponds to the difference in energy levels, which explains why specific wavelengths of light are observed in an emission spectrum.
