Radiation whose wavelengths are among the shortest are gamma rays.

Here's why:

* Electromagnetic Spectrum: The electromagnetic spectrum encompasses a wide range of radiation, from low-energy radio waves to high-energy gamma rays.

* Wavelength and Energy: Wavelength and energy are inversely proportional. This means shorter wavelengths correspond to higher energies.

* Gamma Rays: Gamma rays are the most energetic form of electromagnetic radiation. They are produced by nuclear reactions and radioactive decay.
