A student is using the electromagnetic spectrum to design a device for human communication. The student needs
a wave that has more energy than a radio wave and less energy than an infrared wave. Determine which wave the
student should choose, and describe the wavelength and frequency of the wave compared to a radio wave and
infrared wave.
The student would use ultraviolet waves since they have a shorter wavelength and higher frequency and therefore have less
energy than infrared waves.
The student would use microwaves since they have a shorter wavelength and higher frequency and therefore have more
energy than radio waves.
The student would use microwaves since they have a longer wavelength and higher frequency and therefore have more
energy than radio waves.
The student would use ultraviolet waves since they have a longer wavelength and higher frequency and therefore have less
energy than infrared waves.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
