Nonparticulate - Radiation

The only part of the spectrum detectable by the human eye. Infrared (IR): Experienced as heat.

, more commonly referred to as electromagnetic radiation , consists of energy waves rather than physical particles. Unlike particulate radiation (such as alpha or beta particles, which have mass), nonparticulate radiation is composed of oscillating electric and magnetic fields that travel at the speed of light. Key Characteristics nonparticulate radiation

Nonparticulate radiation spans a wide range of energies, categorized by their wavelength and frequency: The only part of the spectrum detectable by the human eye

Because it has no mass, certain forms (like gamma rays) can penetrate much more deeply into materials than particulate radiation. The Electromagnetic Spectrum which have mass)

Lower-energy waves that lack the power to ionize atoms but can cause thermal effects.
