Do cosmic rays get reflected by a mirror?Just like the normal(visible spectrum) light, do cosmic rays and lasers get reflected by a polished surface or are they strong enough to penetrate through them? (Sangeetha Varma posted this question)
Answer: Cosmic rays are energetic charged subatomic particles, originating from outer space. They may produce secondary particles that penetrate the Earth’s atmosphere and surface. Cosmic rays were thought to be electromagnetic radiation in the past. Most primary cosmic rays entering the atmosphere from deep space are composed of subatomic particles that normally occur on Earth, such as protons, atomic nuclei, or electrons. However, a very small fraction are particles of antimatter, such as positrons or antiprotons. The precise nature of this remaining fraction is an area of active research.
