This unique NASA resource on the web, in print, and with companion videos introduces electromagnetic waves, their behaviors, and how scientists visualize these data. Each region of the electromagnetic spectrum (EMS) is described and illustrated with engaging examples of NASA science. Come and explore the amazing world beyond the visible!
Introduction to the Electromagnetic Spectrum: Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. You depend on electromagnetic energy every hour of every day. Without it, the world you know could not exist.
Anatomy of an Electromagnetic Wave: An electromagnetic wave is made up of changing electric and magnetic fields and is important way that energy is transported in the world around us.
Wave Behaviors: Light waves across the electromagnetic spectrum behave in similar ways and can be transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered
