(a) Briefly describe Bohr's theory of the hydrogen atom and how it explains the appearance of an emission spectrum. How does Bohr's theory differ from concepts of classical physics? (b) Explain the meaning of the negative sign in Equation (7.5).
ANSWER:Step 1 of 3
(a)
According to Bohr's hypothesis, the electron can only occupy certain orbits with specific energies, implying that the electron's energies are quantized. An energized hydrogen atom emits radiation as an electron drops from a higher energy permitted orbit to a lower one, emitting a quantum of energy (a photon) in the form of light, resulting in an emission spectrum.
