Activity 6 - The Electromagnetic Spectrum and Your Community

Use the resources listed below to help you complete this activity.


To learn more about this topic, visit the following web sites:

The Nature of Electromagnetic Radiation

The Electromagnetic Spectrum, NASA
This home page provides links to two different topic levels, the second slightly more advanced than the first. The topics for Level One include: Measuring the Electromagnetic Spectrum, A Radio Wave Is Not a Gamma-ray, a Microwave Is Not an X-ray... or Is It?, Why Do We Have to Go to Space to See All of the Electromagnetic Spectrum?. The topics for Level Two include: More about the Electromagnetic Spectrum, and Space Observatories in Different Regions of the EM Spectrum.

All About Spectra, University of Illinois
Try another brief overview on electromagnetic spectrum and electromagnetic wave radiation.

Astronomy and the Electromagnetic Spectrum

An Introduction to Radio Astronomy, National Radio Astronomy Observatory
The NRAO web site offers an education section with various resources including background information and a photo gallery. The Introduction to Radio Astronomy is particular page that offers answers to frequently asked questions about radio astronomy, an article about the VLA and VLBA in New Mexico, and more.

The Electromagnetic Spectrum
Offers a good description of important properties of the major regions of the spectrum.
