LECTURE 31
questions after lecture
first try these again
now think about these
- Why is it surprising for a wave to have energy exactly proportional to frequency? Give an example of a classical wave which definitely does not have this property.
- What are the surprising things about shining visible and UV light on materials to try to get electrons out?
- Why does UV light set electrons free but visible light doesn't?
- How many UV photons does it take to set free an electron?
- On the energy diagram of the photoelectric effect, what is the significance of the slope of the line in the positive energy region showing E versus f?
- How can you increase the kinetic energy of a liberated electron?
- Give the names and definitions of G, c, e, h, k.
- What is quantization?
