The laws of geometric and wave optics are considered, the quantum properties of radiation, the foundations of quantum optics, the elements of quantum mechanics, atomic and nuclear physics, and elementary particle physics are discussed. The most important achievements in modern science and technology are taken into account, great attention is paid to the physics of various natural phenomena. The purpose of the book is to help master the material of the program, to teach to actively apply the theoretical foundations of physics as a working apparatus that allows solving specific tasks related to increasing resource efficiency. The manual is focused on the organization of independent work of students . It analyzes the solution of many physical problems and provides problems for independent solution and answers to them. Prepared according to the program of the physics course of higher technical educational institutions in full compliance with the requirements of the educational state standard . Conforms to the innovation policy and is aimed at the activation of scientific thinking and cognitive activity of students . It is intended for interuniversity use by teachers and students of technical specialties of full-time and distance forms of education . ;Griff:Adopted by the NMS in Physics of the Ministry of Education and Science of the Russian Federation as a teaching aid for university students studying in technical areas of training and specialties
