Which Wave Has the Longest Wavelength and Which Has the Shortest?

Wavelength is the distance between consecutive peaks of a wave, and it plays a significant role in determining the properties of different types of waves in the electromagnetic spectrum. Radio waves have the longest wavelengths, ranging from millimeters to kilometers. They are used for communication, such as in radio broadcasts and cell phone networks. On the other hand, gamma rays have the shortest wavelengths, less than 0.01 nanometers. These high-energy waves are used in medical treatments, like cancer therapy, but can be harmful due to their ability to ionize atoms. Wavelength is inversely related to frequency and energy, with longer wavelengths having lower frequencies and less energy.
