Choose a technology device that makes use of the EM Spectrum. Next, explain how this device works using terminology learned in this chapter.

Explanation / Answer

The benefits of space exploration can hold the key to the future of the human race. Therefore, exploration not only becomes important but necessary. However, these days we use mechanical instruments rather than humans to explore the universe.

We use the EM spectrum for almost any form of communication channel from cellphone to radio to the wifi.
EM Waves in the visible zone help in photosynthesis by supplying the necessary energy. If this were not enough, the vision we experience is due to EM spectrum.
