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.
