1. In terms of heat generated, why are compact fluorescent lamps (CFLs) more efficient than incandescent lamps?

2. A person in your discussion group says that changing electric and magnetic fields generate each other and this gives rise to visible light when the frequency of the change matches the frequency of light. Do you agree? Explain.
