The Electromagnetic Spectrum Interactive Infographic is full of information about electromagnetic waves. There's so much to explore and digest that it will take several sittings before you're satisfied. And even then, you're likely to return for more. Originally created in 1944 as a wall-sized poster distributed by the W.M. Welch Scientific Company (a scientific supply house that has sinced closed its doors), this timeless piece of science and art is now available as an interactive app that allows learners to tap and explore its many layers of information.
For now, users are encouraged to open the Interactive and explore. We have prepared a classroom-ready exercise for those wishing to have a more directed experience. The exercise was modeled after the Waves strand of the Next Generation Science Standards. View
