This course covers Thermodynamics, Waves and Physical Optics, Quantum Physics, Relativity, and introductory Atomic Physics. A foundation of waves and harmonic motion is presented, then optics is presented including physical optics. These concepts are then used to provide a basic understanding of quantum physics and mechanics, including the concepts of quantization of energy and other characteristics and the structure of the atom. Relativity is also presented as a modern physics topic.The material covered in this course is as follows:

The classroom’s main activity is lecture interspersed with questions and discussion. Problems are assigned to be completed by the student. There are three hourly exams.
Students are expected to gain competence in writing, reading, and understanding scientific and mathematical material through participation in a weekly laboratory exercise. The students’ grades are based on experimental techniques, results and written reports.
The main emphasis of this course is to learn to analyze problems and to be able to apply the proper equations and mathematical procedures to obtain a numerical solution.The final grade is apportioned among:
90-100% = A
80-89.9% = B
70-79.9% = C
60-69.9% = D
60% and Below = F
