#### General Competencies

Students completing this course will: understand, appreciate and utilize basics of optics, wave theory and atomic physics in modern technologies and its devices; understand the fundamental principles of physics to prepare students to continue education in modern science and technology, as well as forming a foundation for life-long learning.

#### Learning Outcomes

1. Analyze mechanical oscillatory systems.
2. Apply the linearization technique to equations of motion of the oscillatory systems.
3. Explain the wave equation in non-dispersive medium.
4. Derive the electromagnetic wave equation from the Maxwell’s equations.
5. Explain the phenomena of interference, diffraction and polarization of light.
6. Explain the law of black body radiation by the Planck’s quantum mechanics.
7. Analyze one-dimensional quantum mechanical systems.

#### Forms of Teaching

Lectures

Lectures are delivered to groups of approximately 120 students using electronic presentations, detailed derivations on the blackboard and demonstration experiments.

Exams

Written mid-term exam and the final exam consist of four excercises and a number of multiple choice questions.

Laboratory Work

Students perform six laboratory experiments, carry out the analisys of the measured data and write the final report for each experiment.

Experiments

Lectures are supported by demonstration experiments that illustrate the concepts of physics. Approximately 30 mins / week.

Consultations

At least once a week each professor is available to the students for consultations.

E-learning

During the semester homework assignments are delivered to the students through the e-learning system Merlin (Moodle).

Other Forms of Group and Self Study

In approximately 4 terms per semester additional exercise-solving skills are demonstrated by assistants.
