- 1. Nuclear physics is the field of physics that studies the nuclei of atoms and the particles contained within them. It explores the forces and interactions that hold the nucleus together, as well as the processes of nuclear reactions such as fusion and fission. Nuclear physics plays a crucial role in understanding the structure of matter, the behavior of stars, and the development of nuclear energy technologies. It also has significant applications in fields such as medicine, radiation therapy, and environmental monitoring. Overall, nuclear physics provides valuable insights into the fundamental workings of the universe at the atomic and subatomic levels.
