Except for the folks in the science community, we humans tend to take light for granted. We wake up every morning to see that the sun has risen, and occasionally we take a few minutes in the evening to watch it set. But rarely do we stop and consider what light and the sun which provides it really mean to us as living, functioning organisms.
The light we can see with our naked eyes is but a tiny fraction of all the light emitted by the sun and many electrical gadgets. The various wavelengths of light differ greatly from one another in intensity, energy levels and physical properties. For example, visible light allows us to see the things in the environment around us, while radio waves bring us our favorite radio and television programs and X-RAYS help our doctors keep us alive and in good health.
Every “band” in the entire electro-magnetic spectrum has a purpose, but only the Creator Himself knows what each and every one of them is and what many of their unique properties are. But there are many rather interesting facts about light that we do know, and Michael Schirber lists and explains a number of them in this article on the website LiveScience.com. Check it out!
