Learning Goals:
As you work through this unit, you should be able to understand and demonstrate these Big Ideas:
- How do emission and absorption spectra occur?
- How does the photoelectric effect exemplify the particle nature of light, and how does the de Broglie hypothesis suggest the wavelike nature of particles
- How are the concepts of momentum and energy in collisions applied to the scattering of photons by electrons?
- How are mass–energy equivalence and charge and nucleon conservation laws applied to nuclear reactions?
Today:
- Lasers Simulation - what does it take to get it to lase? Change the variables to make it happen.
- Watch these videos for clues: Minute Physics and Smarter Every Day
- How does this relate to atomic quanta, absorption and emission?
