Educators, if you are looking for additional lessons on the Electromagnetic Spectrum, check out the Satellite Meteorology module, How Light (Electromagnetic Radiation) Enables Satellites to Produce Images. The module reviews the basics of the electromagnetic spectrum and makes the connection between radiation theory and the images we get from weather satellites.
For more information and a link to the activity, consult the article in NEON in the Satellite Meteorology forum.
