Laboratory work in physics . Atomic physics: the Frank and Hertz experience, the Compton effect, the Messbauer effect" is an indispensable educational material that will help students and teachers to better understand the complex concepts of atomic physics through practical application. Compiled by a team of authors, this book is not just a collection of laboratory work, but a guide to key experiments that have become the basis for modern understanding of atomic structure and interactions. The book focuses on three significant experiments: the Frank and Hertz experiment, the Compton effect, and the Messbauer effect. Each of these experiments not only illustrates the theoretical aspects of atomic physics, but also shows how scientific discoveries can be achieved through practical research. The Frank and Hertz experiment, for example, was an important step towards the discovery of quantum energy levels in atoms, and the Compton effect demonstrated the corpuscular-wave nature of light. The Messbauer effect, in turn, opened up new horizons in nuclear physics and spectroscopy. The book will be of particular interest to physics students, graduate students and teachers who seek not only to master the theory, but also to put it into practice. It can also attract the attention of science lovers who want to expand their knowledge of fundamental experiments that have changed our understanding of nature. The age category of readers - from high school students studying physics to adults seeking self-education in this area The topics raised in the book concern not only physics as a science, but also philosophical questions about the nature of matter and light. How do particles interact? What are the implications for our understanding of the universe? These questions make the book not only a textbook, but also a source for thinking about man's place in the world of science. The style of the authors is distinguished by clarity and accessibility, which makes complex concepts understandable even for those who are just starting their way in physics. Each laboratory work is accompanied by detailed instructions, explanations and recommendations, which allows the reader not only to repeat the experiment, but also to understand its meaning. In this regard, the book resembles other well-known works in the field of scientific literature, such as Richard Feynman's Physics for All or Stephen Hawking's A Brief History of Time, which also seek to make complex ideas available to a wide audience. "Laboratory work in physics . Atomic Physics is not just a textbook, but a whole world into which the reader can immerse himself by exploring the laws of nature and discovering the amazing phenomena that shape our world. If you are looking for a book that will help you not only to learn, but also to be inspired by new discoveries, then this edition will be an excellent choice. Do not miss the opportunity to become part of a fascinating journey into the world of atomic physics, where each experiment is a step towards understanding the majestic structure of our being.
