Electromagnetic Spectrum

NASA’s Science Mission Directorate has produced a thirty minute video Tour of the Electromagnetic Spectrum, the first third of which is unqualifiedly excellent. Superb imagery, vivid illustrations and precise commentary make it exemplary.

Unfortunately, twelve minutes and fifty four seconds into the video, the visual display begins an expert analysis of the infrared portion of the electromagnetic spectrum, while the audio portion, with equal expertise, begins to discuss visible light. While both the commentary and the video continue to be exquisite, they remain unsynchronized for the final 18 minutes of the presentation.

Strangely, despite this flaw, this educational video is well worth a look – particularly the first 13 minutes.

  1. This is just to say that I discovered you by accident (while searching for an archaeopteryx drawing); I love your site. I will make sure to show it to my kids, about 9 hours time difference from Haysville.
