Evidence that the perceived color of an object depends on the material it is made and the light incident on it.

The electromagnetic spectrum simulation takes the opportunity to show the wavelengths and frequencies related to each radiation.

Everything in our universe is made up of a very small numbers of particles, and is controlled by just four forces. In this Hangout, we will discuss these basic building blocks of everything.

Beginning from an exploration of astronomical objects, using Messier Bingo, this scenario explores the Universe across the electromagnetic spectrum.

Welcome to the Tour of the Electromagnetic Spectrum. 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 spectrum is described and illustrated with engaging examples of NASA science. Come and explore the amazing world beyond the visible!
