Which statement correctly describes gamma radiation among the following?

• A. They are charged particles emitted by the nucleus
• B. They have the greatest mass among the radiation types
• C. They are neutrally charged particles emitted during decay
• D. They are electromagnetic waves with the shortest wavelengths and highest frequencies

Answer: (D)

Gamma radiation are high-energy photons, a form of electromagnetic radiation emitted by a nucleus when it changes state. Photons have no rest mass and carry no electric charge, so gamma rays are not charged particles. They are not massive particles emitted during decay, and among radiation types they sit at the high-energy end of the electromagnetic spectrum, giving them the shortest wavelengths and highest frequencies. This short wavelength corresponds to their strong penetrating power and energy, which is why gamma rays behave differently from alpha or beta radiation.
