Tour of the Electromagnetic Spectrum

This publication introduces the electromagnetic energy and the properties of electromagnetic waves across the spectrum. Each wavelength is shown with stunning NASA imagery with explanations of how NASA instruments collect data to help study Earth and space.

Tour of the Electromagnetic Spectrum

Every day, electromagnetic waves surround us. We use these waves, but we can see only a small portion of them. They carry our cellphone calls and radio broadcasts, heat our food, and let us see in the dark. This resource presents the electromagnetic spectrum by introducing how we interact with these waves on a daily basis and how NASA scientists use the unique qualities of each wavelength to study the sun, planets and origins of the universe. EM waves measured by Earth-observing satellites help NASA scientists understand our Earth system and changing global patterns and climate. These materials are designed as supplemental instruction and can be used in formal classroom or informal settings for students in grades 5-12, undergraduates, or adults.
