Laboratory work in physics . Quantum optics, photoelectric effect, nuclear magnetic resonance . Training manual C" is a unique training manual created by a team of authors, which will become an indispensable assistant for students, graduate students and anyone interested in physics at a deeper level. This publication is not just a set of laboratory papers, but a whole world in which readers are immersed, seeking to understand the complex concepts of quantum physics and their practical application. The book covers three key aspects of physics: quantum optics, photoelectric effect, and nuclear magnetic resonance. Each of these sections represents a separate world full of mysteries and discoveries. Quantum optics, for example, explores the behavior of light at the quantum level, opening doors to the amazing world of photons and their interaction with matter. Readers will be able to learn how these processes affect our perception of light and how they are used in modern technologies, such as lasers and optical systems. The photoelectric effect, in turn, demonstrates how light can cause electrons to eject from matter, which was one of the first confirmations of the quantum nature of light. This section of the book not only explains the theory, but also offers practical experiments that will help to better understand this phenomenon. Nuclear magnetic resonance (NMR) is another exciting topic that opens new horizons in medicine and chemistry, allowing the study of the structure of molecules and tissues. The book offers readers not only the theoretical foundations of NMR, but also step-by-step instructions for conducting their own experiments. This book will be of interest to physics students, graduate students, teachers and anyone who wants to deepen their knowledge in the field of quantum mechanics and its applications. It is suitable for both those who are just beginning their journey in physics, and for experienced researchers seeking to refresh their knowledge and skills. Thanks to an accessible language and a clear structure, the material is easily digestible, and practical tasks allow you to consolidate the knowledge gained. The topics raised in the book are relevant and important for modern society. Quantum physics is the foundation of many of the technologies we use every day, from smartphones to medical equipment. Understanding these processes helps not only in learning, but also in professional activities. The book emphasizes the importance of experimentation in physics, showing that theory and practice must go hand in hand.. The style of the authors is distinguished by clarity and accessibility, which makes complex concepts more understandable. Their experience and knowledge of the subject make it possible to create a manual that is not only informative, but also inspiring. The team of authors includes both experienced teachers and young scientists, which gives the book a fresh look at traditional topics. If you are looking for a tutorial that will help you not only learn quantum optics, photoelectric effect and nuclear magnetic resonance, but also learn how to apply this knowledge in practice, then "Laboratory work on physics . Quantum optics, photoelectric effect, nuclear magnetic resonance . Training Manual C" will be your reliable companion in this fascinating journey.
