Though even if you consider them as waves they don't depend on "jiggling" of a medium. That medium was called the "luminiferous aether" (aka ether), and in the 19th century experiments showed conclusively that it doesn't exist: http://en.wikipedia.org/wiki/Luminiferous_aether -- Grant Edwards grante Yow! ..
