It travels in a wave-like pattern and can move through a vacuum, such as outer space.
Because it has no mass, certain forms (like gamma rays) can penetrate much more deeply into materials than particulate radiation. The Electromagnetic Spectrum nonparticulate radiation
Responsible for sunburns and used in sterilization. It travels in a wave-like pattern and can
Nonparticulate radiation lacks mass and charge, existing purely as "packets" of energy called photons. nonparticulate radiation
Lower-energy waves that lack the power to ionize atoms but can cause thermal effects.
The only part of the spectrum detectable by the human eye. Infrared (IR): Experienced as heat.
Frequently used in medical imaging to view internal structures.
