Electromagnetism is all around us and is essential to the world in which we live.
We rely on electromagnetic waves to heat our food, carry cell phone calls, and even bring music to the radios in our cars. But how does NASA sense this energy to study vegetation on Earth, monitor solar eruptions on the Sun, or detect elements on another planet?
This iBook provides animation and interactive graphics to illustrate electromagnetism and its associated wave properties. NASA imagery and spectral signatures demonstrate how NASA instruments harness the unique qualities of each wavelength to help study the dynamic properties of our Sun, the complexities of our Earth System, and the origins of the universe.
