28. Final Jeopardy Question:
When I put zinc nitrate into a flame, a bright red flame is produced. What is happening to the zinc’s electrons and what does that specific color tell us about the energy, wavelength and frequency of the light wave?
Answer:
The electrons are jumping energy levels and releasing red light wave photons as they fall back to ground state. Big wavelengths, low frequency, low energy.
