Answer:
a) Gamma Rays
Explanation:
Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies, this range of wavelengths is known as electromagnetic spectrum. This spectrum is divided into seven regions with characteristic energy levels, wavelengths, and frequencies associated with its photons.These regions are (from lower to higher energy) radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays, following this order Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. You can see this in comparison with the rest of the spectrum in the image I added.
