8.Give an example of a poor blackbody radiator and explain why it is not a good blackbody radiator.
9. Does a blackbody radiator emit light waves? Explain.
10. What is the relationship between the energy of a wave and its frequency?
11. What name has been given to Max Planck's "packets of light"? What does it mean to say that the packets are "quantized"?
12. What is the photoelectric effect, and what experimental evidence led scientists to discover it? Does this support the wave or particle theory of light? Why?
13. Explain why the wave model of light cannot explain the energy emissions from a blackbody radiator, but the particle model of light can.
