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