The electromagnetic spectrum

Interactive Simulator · The electromagnetic spectrum

Move along the spectrum and watch wavelength and frequency trade off through c = fλ, with the named regions and the narrow visible band marked.

Mission Predict how the wavelength changes as you move from radio toward gamma. Streak 0Best 0
