Bohr model Transitional Reasoning Practice

Questions

1. 1.

   An experiment measuring the visible emission spectrum of atomic hydrogen reveals that an electron transition from the $n = 3$ orbit to the $n = 2$ orbit produces red light, whereas a transition from $n = 4$ to $n = 2$ produces cyan light of higher frequency. According to Niels Bohr's atomic model, which deduction accurately explains the origin of this frequency difference?

   • A) Electrons continuously radiate electromagnetic energy while orbiting the nucleus, so electrons in higher orbits accelerate more rapidly toward the nucleus.
   • B) Light is emitted when an electron absorbs external energy to transition from a lower-energy orbit to an excited state farther from the nucleus.
   • C) The orbital energy gap between $n = 3$ and $n = 2$ is wider than that between $n = 4$ and $n = 2$, which causes the release of higher-energy photons.
   • D) The energy of an emitted photon equals the difference between two discrete stationary states, meaning the larger energy gap from $n = 4$ to $n = 2$ yields a photon of higher frequency.
