The Book of Physics . Part 3 . Wave optics, quantum nature of radiation, elements of quantum mechanics, elements of quantum theory of solids" authored by Gorbatov B. and . and Poleva V. F. It is a fascinating and deep dive into the world of physics, covering key aspects of wave optics and quantum mechanics. This publication will be an indispensable assistant for both students and teachers seeking to understand the complex concepts behind the behavior of light and matter. The book begins with a discussion of wave optics, where the authors explain in detail the nature of light as waves, considering phenomena such as interference and diffraction. The reader will be able to learn how these phenomena affect everyday life, from the simplest optical devices to complex technologies used in science and medicine. Intriguing examples and practical tasks will help to consolidate theoretical knowledge, making the learning process fascinating and accessible. Next, the authors move on to the quantum nature of radiation, revealing surprising aspects that call into question the usual ideas about the world. Here, the reader will come across the concept of photons, energy quantization, and the uncertainty principle. This is not just a set of formulas and theories, but a real philosophy that makes you think about the nature of reality. The book invites readers not only to study the theory, but also to understand how these principles are applied in modern technologies, such as lasers and semiconductors. Particular attention is paid to the elements of quantum mechanics and quantum theory of solids. In this section, the authors look at complex systems such as crystals and their properties, which opens the door to understanding modern materials and their applications in electronics and nanotechnology. Readers will be able to see how quantum mechanics underpins many of the innovations that shape our future. The Book of Physics .
