The Question
(Submitted February 06, 1997)
Where can I get a poster of the electromagnetic spectrum? I have seen them
at some places. If you know it would be greatly appreciated.
The Answer
Unfortunately I do not know where to get an electromagnetic
spectrum poster.
Two nice catalogs for stuff like this are:
1. Sky publishing: http://skyandtelescope.com
2. The Astronomical Society of the Pacific
http://www.astrosociety.org
However, neither one has an electromagnetic spectrum poster
in its current catalog.
Good Luck,

PS. A reader of this site has pointed out that such a poster can be
obtained free of charge from Wright Center for Science Education
http://www.tufts.edu/as/wright_center/svl/posters/posts.html.
Teachers can obtain the printed version free via mail; anybody can download
the zipped jpeg file, which, however, does not have a sufficient resolution
for the text to be legible.
PPS. Another reader recommended the online catalogue from
Exploratorium in San Francisco as another possible resource. See
http://www.exploratoriumstore.com/.
