What causes the emission of distinct spectral lines when light from an excited gas discharge tube is passed through a prism?
Answer and explanation
Correct answer: A. electrons transitioning from higher quantized energy levels to lower ones
- Step 1: Electrons in excited states drop to lower discrete orbitals, releasing photons with energy Delta E = h f. Step 2. Since energy levels are quantized, emitted light produces discrete spectral lines. Answer: electrons transitioning from higher quantized energy levels to lower ones. Why not the others:* Bremsstrahlung produces a continuous spectrum.
