Above gamma rays in terms of frequency and energy are cosmic rays. These are highly energetic particles from outer space that can originate from the sun or other astrophysical sources. While gamma rays are the most energetic form of electromagnetic radiation, cosmic rays consist of charged particles, such as protons and atomic nuclei, traveling at nearly the speed of light.

FAQs & Answers

  1. What are cosmic rays? Cosmic rays are highly energetic charged particles, such as protons and atomic nuclei, that originate from outer space and travel at nearly the speed of light.
  2. How do cosmic rays differ from gamma rays? Gamma rays are electromagnetic radiation with the highest energy in the electromagnetic spectrum, while cosmic rays are charged particles with even higher energy that come from sources like the sun and other astrophysical events.
  3. Where do cosmic rays come from? Cosmic rays originate from various sources, including the sun and other distant astrophysical sources such as supernovae and active galactic nuclei.
