The course is one of the compulsory specialization courses for students in the physics program and the course aims to qualify students theoretically and practically so that they can continue their higher studies on the one hand and play a distinguished role in research, and qualify students theoretically and practically and work in scientific and industrial institutions, the importance of modern physics lies in that it has entered into all fields such as (X-rays, detection of cancerous tumors, magnetic resonance and others), The student also learns the most important concepts and basic principles of the theory of special and general relativity, as well as atomic models, finding the radii of orbits, as well as understanding the subject of X-rays, which qualifies them to work and research in all fields.
