School of Physics and Technology of University of Kharkiv now being carried by the department. The department is considered to be the most difficult department at the school. Students of the department study special courses on elementary particles, quantum electrodynamics, general relativity, astrophysics, theoretical nuclear physics, solid-state theory, and plasma physics. In addition, the professors of the department teach most of the bachelors-level mathematics and theoretical physics courses at the school. The department was created in 1937 by Anton Valter. The name of the department changed several times: "Department of Physics of the Atomic Nucleus", "Department of Physics of the Atomic Nucleus and Electronics", "Department of Electronic Processes", "Department
Electromagnetic radiation of it is not ionizing, because UV can damage molecules due to electronic excitation, which is far greater per unit energy than heating effects. Infrared radiation in the spectral distribution of a black body is usually considered a form of heat, since it has an equivalent temperature and is associated with an entropy change per unit of thermal energy. However, "heat" is a technical term in physics and thermodynamics and is often confused with thermal energy. Any type of electromagnetic energy can be transformed into thermal energy in interaction with matter. Thus, "any" electromagnetic radiation can "heat" (in the sense
