The Electromagnetic Spectrum
Test your knowledge of the electromagnetic spectrum — the full range of radiation from radio waves to gamma rays, and what each part is used for.
Fourteen questions cover wavelength and frequency, the uses of each spectrum region, and calculations linking speed, wavelength, and frequency.
A challenging check for anyone who wants to actually understand what separates a radio wave from an X-ray.
