Radiation is classified as a form of what?

Radiation is classified as a form of energy because it involves the transmission of energy through space or a medium. In the context of physics, radiation refers specifically to the emission and propagation of energy in the form of electromagnetic waves, such as visible light, gamma rays, and x-rays, as well as particle radiation, like alpha and beta particles.

This categorization underlines the fundamental nature of radiation, which is characterized by quantum energy packets known as photons in the case of electromagnetic radiation. These photons carry energy and can interact with matter, leading to various effects like ionization or heat production. Understanding radiation as a form of energy is crucial in fields such as radiology, nuclear physics, and energy production, as it influences how radiation is harnessed, measured, and controlled for various applications.
