Assignment

1. Explain what you learned about the quantization of radiation from the Franck-Hertz experiment.
2. By working the simulation, find out the different quantized energy levels of Mercury and Neon. Also account for the peaks in the Voltage-Current characteristics.
3. What happens when the accelerating potential reaches 4.9 eV for Mercury and 18.3 eV for Neon, and why?
4. What is the difference between elastic and inelastic collision?
5. Why are electrons used to excite atoms?
6. What happens when an electron collides with a nucleus?
