The first part of this course discusses the questions "what is light? and "how does light behave? Ray theory will be used to investigate the reflection and refraction in simple optical sytems containing lenses, mirrors and prisms. The interference, diffraction and polarization phenomena will be examined by using the wave theory of light.    

The objective of the second part of this course is to enable students to have an appreciation of the concepts and methods of the 20th century physics so known as modern physics. The concept of relativity, the wave-particle duality, Bohr model of the atom, the nucleus and the introductory ideas of the quantum mechanics will be discussed.
