Electromagnetic Spectrum

I’ve come across this information graphic that visualizes the electronmagnetic spectrum. Unfortunately there seems to be no information about the creator or if the poster is available in any way. The only indication of it’s origin is the Westinghouse logo (Westinghouse Research Laboratory to be exact). If we put aside the warm feelings we have by looking at such a density of information, we may see some difficulties with the readability of the skewed diagrams. Nonetheless it’s a solid piece of work with a clear focus on details and elaborateness. Interested in how to dump down the richness of information? Here’s the “chart junk” version of the same concept.

    Where did you find the graphic above? I’d love to purchase one to have in my study. It would make a great chart for the kids/grandkids. Any help would be great, thanks!

      Unfortunately I can’t name the exact source. I found it via RobotNinja and it’s apparently done by the Westinghouse Research Lab.

      If you find the actual source, it would be nice if you could share it with us.

    The chart in question was produced by my father, C. Howard Jones while he was an advisory engineer at Westinghouse Research Lab. My two brothers and I helped to color the draft copies of the chart prior to the Westinghouse production department making the final version. Another firm later produced a version of the chart – less colorful! The origional received a Cameo in the movie Discosure (Michael Douglas and Demi Moore). The later version was on a wall of a lab in Jag the TV series and is on the wall of the appartment used for the TV series “The Big Bang.” Of course the original is on laboratory and classroom walls throughout the world!

      Thanks for the explanation Mark. As I still got some space left on my walls, is there a possibility to get a copy of this poster?

      I will second Mr. Wiederkehr’s question. It’s a brilliant piece of work, however fussy certain folks might be about the exact representation of the wealth of information presented.

    The chart is still available at the Exploratorium — I give it to teachers when I demonstrate my lesson plan for introducing middle-grade students to the “Total EM Spectrum – In ONE LESSON!”

    I'm currently negotiating with NASA and Kurt Feichmeir at the Exploratorium to help NASA acquire the rights so it can be made available on their website in PDF form so anyone can download and print it at no cost.

    Your comment didn't include when it first appeared — I got my first one at the Pentagon in the early 70's. When did it first became available for Westinghouse to pass it along to folks in the USAF electronic warfare offices at the Pentagon?

    It's still the best representation of all the characteristics of EM radiation — “All the secrets of the universe are there – just waiting to be discovered!” (Paraphrasing Carl Sagan's statement.)

    I'd love to know more about it's development.

    Best Regards, Andy Setlow (aka “Prof Spectrum”)

    Would you like a copy of my lesson plan for introducing middle-grade students to THE TOTAL EM SPECTRUM IN ONE LESSON?

    I have one on the wall of my office. The pain box bottom centre has the following – Westinghouse Electric Corporation, Printing Division, Trafford, PA. 1961, Chart number MB-1937, price $3.50. My copy does not have yellow in the print composition. It is an original copy.
