What is the range of wavelengths and frequencies?

The electromagnetic spectrum encompasses a wide range of wavelengths, from about 10 picometers (10^-12 meters) for gamma rays to over 100 kilometers (10^5 meters) for radio waves. Correspondingly, the frequencies range from approximately 30 hertz (Hz) for long radio waves to over 10^20 Hz for gamma rays. This vast range allows for various applications, including communication, medical imaging, and energy transfer.
