* Gamma rays have a wide range of wavelengths: Gamma rays are a form of electromagnetic radiation, just like visible light, radio waves, and X-rays. However, they have the shortest wavelengths and highest frequencies within the electromagnetic spectrum.
* The range of gamma ray wavelengths is vast: They can range from picometers (10^-12 meters) down to fractions of a femtometer (10^-15 meters).
Instead of a single wavelength, we talk about the energy of gamma rays: Physicists often describe gamma rays in terms of their energy, measured in electron volts (eV). This is because the energy of a gamma ray is directly related to its frequency and inversely related to its wavelength.
So, to talk about a specific gamma ray, you'd need to specify its energy, not its full wavelength.
