Um, time to update you imagery, NASA.

Research on radio waves with my daughter this morning led to NASA’s informative, if somewhat visually outdated, legacy page: http://science.hq.nasa.gov/kids/imagers/ems/radio.html

"Why are antennae on your cell phones smaller that antennae on your radios?"

So glad this is lingering on a server somewhere. The updated page is not nearly as fulfilling: http://missionscience.nasa.gov/ems/05_radiowaves.html
