Electromagnetic Spectrum

Electromagnetic Spectrum Activity

This interactive is a resource guide to the electromagnetic spectrum. After the introduction screen, use a slider to select and learn about specific wavelength ranges within the EM spectrum. For each wavelength range you can find: a sub-spectrum, a list of natural occurrences and common uses, a photo of the Sun, and a cool fact. Click “SEE SCIENCE IN SPACE” in the lower right-hand corner to explore how NASA uses each particular wavelength range to observe phenomena in space. A waveform above the EM spectrum shows wavelengths in metric units.
