Overview

This course aims to introduce students to basic concepts in modern physics such as the wave behavior of particles, the particle behavior of electromagnetic waves, as well as the photoelectric phenomenon, the Compton effect, and the production of pairs. Also, enable students to study the atomic structure according to modern theories. Provide students with information on the theory of relativity. Introduce students to relativistic mechanics with an introduction to quantum theory.

Intended learning outcomes

At the end of the course the student should be able to:

  1. Learn about the failure of classical physics to explain phenomena such as black body radiation, photoelectric effect and Compton Effect.
  2. Explain phenomena of modern physics such as black body radiation, photoelectric effect and Compton Effect.
  3. Explain the Heisenberg's principle of uncertainty and its proof and applications.
  4. Introduce the relation between classical relativity and modern relativity.
  5. Familiarize the students with the particle-like properties of waves as well as the wave-like properties of particles.
  6. Learn about the x-ray, x-ray production, measuring x-ray intensity, x-ray spectrum and applications associated with x-ray.
  7. Uses mathematical skills in the physics aspects.
  8. Write scientific reports as well as scientific researches of which related to the course topics.

Teaching and learning methods

Lectures.

Discussion and dialogue.

Methods of assessments

The methods of evaluating students in this course are distributed as follows:

o Semester work (40 marks) is divided as follows:

· First written exam (objective questions and problem) (15 marks).

· Second written exam (objective questions and problem) (15 marks).

· Scientific activities (e.g. weekly tests, reports discussion) (10 marks)

o Final: written exam (60 marks).
