Bring spectroscopy to your physics class with this hands-on emissions spectroscopy activity! Fran Poodry, director of physics at Vernier, demonstrates how to use the Go Direct® Emissions Spectrometer and Go Direct SpectroVis® Plus Spectrophotometer to explore electron energy levels with gas discharge tubes. 

Key Takeaways:

  • Examine emissions spectra of incandescent, fluorescent, and LED lighting. 
  • Learn strategies for teaching a modified version of Balmer’s equation to relate the photons’ energies to specific transitions between energy levels.
  • Gain experience using the Go Direct Emissions Spectrometer and Go Direct SpectroVis Plus Spectrophotometer to collect and analyze data.
