The Wave Phenomena at the Border of the Two Environments . Workshop No. 2 is a unique publication created by a team of authors, which will become an indispensable assistant for students, graduate students and teachers in the field of physics and engineering. It deals in detail with wave phenomena occurring at the boundary of different environments, which is one of the key topics in theoretical and applied physics. This book not only deepens the understanding of physical processes, but also helps to develop the practical skills needed to solve complex problems. Wave phenomena are not just abstract concepts, but real processes that affect many aspects of our lives, from sound waves to electromagnetic oscillations. In this book, the authors invite readers to immerse themselves in the world of wave processes, studying their behavior at the boundaries of partitioning environments, such as air and water, or various materials. This allows us not only to understand the theoretical foundations, but also to see how these principles are applied in real-world situations. The book will be of particular interest to technical students studying physics, mathematics and engineering disciplines. It can also attract the attention of teachers who are looking for quality materials for their courses, as well as researchers working in the field of physics and related sciences. It is important to note that the publication is suitable for both beginners and more experienced readers who want to deepen their knowledge in this area. The topics covered in the book cover a wide range of issues related to wave phenomena. Readers will be able to learn about the principles of interference, diffraction and wave reflection, as well as how these phenomena manifest themselves in different environments. The book also contains practical assignments and examples, making it an ideal tool for self-study and exam preparation. Each section is built in such a way that the reader can not only learn the theory, but also apply the knowledge gained in practice. The style of the authors is distinguished by clarity and accessibility, which makes it easy to perceive even the most complex concepts. They use many illustrations and graphs, which helps to visualize the phenomena discussed. In addition, the book includes an extensive set of tasks that stimulate critical thinking and help readers develop analytical skills. If you are looking for literature that will help you to better understand wave phenomena and their practical application, then "Wave phenomena at the boundary of the separation of the two media. Workshop No. 2” will be an excellent choice . This edition will not only enrich your knowledge, but also inspire you to further study physics and engineering. It will become a reliable companion in your educational path, opening the door to new knowledge and opportunities. In conclusion, it is worth noting that this book is not just a textbook, but a real find for everyone who is interested in physics and its applications in real life. By reading it, you will not only expand your knowledge, but also enjoy a fascinating journey into the world of science.
