Electromagnetic Spectrum - Imagine the Universe!
The electromagnetic spectrum can be expressed in terms of energy, wavelength or frequency. Each way of thinking about the EM spectrum is related to the others in a precise mathematical way. Scientists represent wavelength and frequency by the Greek letters lambda (λ) and nu (ν).
Electromagnetic Spectrum - Introduction - Imagine the Universe!
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.
Spectra - Introduction - Imagine the Universe!
But the electromagnetic spectrum encompasses more than just optical light. It covers all energies of light, extending from low-energy radio waves, to microwaves, to infrared, to optical light, to ultraviolet, to very high-energy X-rays and gamma rays.
Regions of the Electromagnetic Spectrum
Astronomer's Toolbox Wavelength, Frequency, and Energy Regions of the Electromagnetic Spectrum Listed below are the approximate wavelength, frequency, and energy limits of the various regions of the electromagnetic spectrum.
Astronomer's Toolbox - Imagine the Universe!
Astronomers need to collect light from across the electromagnetic spectrum to completely understand a celestial object. Use the links below to explore how astronomers use the highest energies of light to learn about our Universe.
Background: Introduction to Spectroscopy - Imagine the Universe!
But the electromagnetic spectrum encompasses more than just optical light - it covers all energies of light extending from low-energy radio waves, to microwaves, to infrared, to optical light, to ultraviolet, to very high-energy X- and gamma-rays.
Observatories Across the Electromagnetic Spectrum
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
Electromagnetic Spectrum Cool Fact - Imagine the Universe!
Electromagnetic Spectrum Electromagnetic Spectrum The amount of energy a photon has makes it sometimes behave more like a wave and sometimes more like a particle. This is called the "wave-particle duality" of light. It is important to understand that we are not talking about a difference in what radiation IS, but only in how it behaves.

What's the Frequency, Roy G. Biv? - Imagine the Universe!
This lesson is based on the concepts of frequency and wavelength, how they relate to each other, and how they correlate with the colors of the visible spectrum.
