A Collection of Questions and Tasks in General Physics . Section 3. Optics. Section 4. Quantum Physics" edited by B. N. Lightweight and authored by H. In. Soina, A. B. Kazantseva, I. A. Vasilieva and G. N. Goltzman is an indispensable tool for students, teachers and anyone interested in physics at a deeper level. This collection is not just a set of tasks, but a carefully thought-out educational material that will help readers master the complex concepts of optics and quantum physics. In the first part of the collection devoted to optics, readers will find a variety of questions and tasks covering basic principles and laws, such as refraction of light, interference and diffraction. These topics are the cornerstones of optics and are of great importance both in theory and in practice. Tasks range from simple to complex, allowing both beginners and more experienced students to deepen their knowledge and skills. Each task is accompanied by detailed explanations and solutions, which makes the learning process more accessible and understandable. In the second part, devoted to quantum physics, readers are immersed in the world of microparticles and their strange but amazing properties. Topics such as quantum superposition, the uncertainty principle and quantum entanglement are considered through the prism of practical problems that will help consolidate theoretical knowledge. This part of the collection is especially interesting for those who want to understand how quantum physics changes our view of the world and opens up new horizons for future technologies. The book will be especially useful for students of physical and mathematical specialties, as well as teachers who are looking for high-quality materials to prepare for classes. It can also be of interest to high school students passionate about physics, and all science lovers seeking to expand their horizons. The collection is suitable for self-study, and can also be used as an auxiliary material in lectures and seminars. The topics raised in this collection are relevant and important because they relate to the fundamental principles on which many modern technologies are based from optical devices to quantum computers. Understanding these concepts not only enriches knowledge, but also forms the critical thinking needed to solve complex problems in science and technology. The style of the authors is distinguished by clarity and accessibility, which makes the material easy to perceive. They are able to explain even the most difficult things in simple language, which is especially valuable for students who may encounter difficulties in studying physics. In their arsenal there are other well-known works that also deserve attention, such as the “Collection of Problems in Mechanics” and the “Course of General Physics”, which will help to deepen knowledge in other areas of physics. If you are looking for quality teaching material that will help you understand optics and quantum physics, this collection will be an excellent choice. It will not only expand your knowledge, but also inspire you to further study physics and its amazing aspects. Do not miss the opportunity to immerse yourself in the world of science with the "Collection of questions and problems in general physics" - your reliable assistant on the way to understanding complex physical phenomena!
