Gamma rays were discovered in 1900 by French physicist Paul Villard while studying radioactivity in radium. Unlike alpha and beta rays, gamma rays could penetrate through materials, indicating their high energy. Villard's discovery was further confirmed by Ernest Rutherford, who named them gamma rays.

FAQs & Answers

  1. What are gamma rays? Gamma rays are high-energy electromagnetic radiation produced by nuclear reactions and certain celestial events.
  2. Who first discovered gamma rays? Gamma rays were first discovered by French physicist Paul Villard in 1900 while he was studying radioactivity.
  3. Why are gamma rays important in physics? Gamma rays are crucial for understanding high-energy processes in the universe and have applications in medicine, such as cancer treatment.
  4. How do gamma rays differ from alpha and beta rays? Unlike alpha and beta rays, gamma rays are massless and have a much higher penetration power, making them more energetic.
