There are many wavelengths of light and radio waves, and we encounter them 24/7 even while sleeping. We use telescopes to travel back in time to view our beginnings, and appreciate sunlight and light bulbs to get through our day. I find our site full of promise dealing with light (lidar) and radar (radio waves beyond the visible). As a lifelong subscriber to Nasa Tech Briefs, Photonics Spectra, Biophotonics, Astronomy, Sky, and white papers on the aforementioned, I see a beautiful thing when it all comes together called "the science of radiation." I'm glad I've joined you.
