Which of the following has the highest energy?

Gamma rays have the highest energy among all types of electromagnetic radiation. In the electromagnetic spectrum, energy increases as the wavelength becomes shorter. Gamma rays have the shortest wavelengths and highest frequencies, which means they carry the most energy. X-rays and ultraviolet radiation have less energy than gamma rays. Radio waves have the lowest energy because they have the longest wavelengths and lowest frequencies. So, the correct answer is gamma rays.
