Emission and Absorption Spectra

Mr. Anderson explains emission and absorption spectra using hydrogen gas. He describes how electrons in atoms emit or absorb photons when transitioning between energy levels, highlighting the conservation of energy. The video uses a PHET simulation to demonstrate these concepts and compares spectra from different elements like mercury and neon. The analysis of visible light and its spectrum is also covered, emphasizing the importance of specific photon energies for electron transitions.
