Verified step by step guidance1
Understand that electromagnetic radiation consists of waves of electric and magnetic fields that travel through space at the speed of light.
Recall that electromagnetic radiation includes a spectrum of waves such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Recognize that alpha particles and neutrons are types of particles, not waves, and sound waves are mechanical waves requiring a medium, not electromagnetic waves.
Identify gamma rays as a high-energy form of electromagnetic radiation, which fits the definition perfectly.
Conclude that among the options given, gamma rays are the correct form of electromagnetic radiation.
