Which of the following is a type of electromagnetic radiation?

Alpha
Gamma
Infrared
Beta

The correct answer is: Gamma

Electromagnetic radiation is a form of energy that is propagated through space via oscillating electric and magnetic fields. It encompasses a wide range of wavelengths and frequencies, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Out of the given options A, C, and D, only gamma represents electromagnetic radiation. Option A, alpha, is a type of radiation emitted by radioactive elements such as uranium and radium. This form of radiation consists of particles (alpha particles) made up of two protons and two neutrons, which are not considered electromagnetic radiation. Option C, infrared, is a type of radiation with longer wavelengths than visible light. It is often referred to as "heat radiation" and is commonly used in heat-sensing equipment, but it is not considered electromagnetic radiation. Option D, beta, is a type
