1. Should the federal government be allowed to control the frequency bandwidths for communication? Support your argument.
2. How are thermograms (infrared photographs) used to help in energy efficient building design?
3. Defend the importance of gamma rays in treating cancer, even though many patients suffer serious side effects to such treatment.
4. If radio waves are not compressional waves like sound waves, explain what their role is in enabling us to hear music from a radio station.
5. How is the depletion or thinning of the ozone layer related to increased ultraviolet radiation? What measures can we take to stop the depletion of
the ozone layer? What can we do to prevent exposure to ultraviolet radiation?
6. Research the ozone layer of our atmosphere and which frequencies it blocks and which it lets through. Recently, ozone holes have been in the news. What are the consequences to the Earth under the holes in the ozone?
7. Research the System International (SI) Prefix units used in the metric system. Convert the wavelength units listed in the Electromagnetic Spectrum from
scientific notation to their proper prefix units ranging from femto units to mega units.
8. Compare and contrast laser light, fluorescent light and incandescent light.
9. How do laser printers and dvd players use laser light?
10. Why are parabolic shaped dishes used to receive low energy electromagnetic waves such as radio waves or television signals?
