It travels in a wave-like pattern and can move through a vacuum, such as outer space. 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 The only part of the spectrum detectable by the human eye
