Course Description

This course covers the physics of waves on strings, electromagnetic waves, physical and geometrical optics, interference, diffraction, and image formation. Emphasis is on physical concepts and mathematical methods that are applicable to many areas of physics. The course comprises three parts: (1) Wave motion, (2) Geometrical Optics and (3) Introduction to Optical Instruments. The first part of the course begins with a brief study of periodic vibrations (simple harmonic motions) and continues with a systematic study of waves: wave motion, wave equation, propagation of elastic waves in a solid and in a spring; harmonic waves and their properties, superposition principle for waves, interference of waves, standing waves in a string and column of air; and the classical and relativistic Doppler Effects. In the second part of the course, students state and use the Huygens’ and the Fermat’s principles to derive the laws of reflection and refraction. A systematic study of spherical mirrors, thin lenses and optical instruments is done. In the last part of the course, the Huygens’ Principle is used to briefly describe the phenomena of interference and diffraction of light. Properties of electromagnetic waves are studied, with a focus on visible light. Topics include wave motion, interaction of electromagnetic waves with matter, geometrical and physical optics, polarization, optical instruments, holography, laser physics and quantum optics at an intermediate level. The course provides the foundation for applied photonics, imaging, laser physics and optical spectroscopy techniques.

 

Course Aims and Objectives

 

By the end of the course students should be able to:

  • Infer and explain the fundamental phenomena of reflection, refraction, interference, diffraction and polarization. 
  • Become familiar with additional relevant mathematical techniques and other powerful tools for tackling a wide range of topics in optics, including formal methods in classical and quantum physics;
  • Attain a common level in basic mathematically- based physics, and so lay a secure foundation in physics for applied photonics, imaging, laser physics and optical spectroscopy techniques.
  • Further develop their experimental skills through a series of class-based experiments, some of which also illustrate major themes of the lecture courses, and developed their communication skills through group activities.
  • Develop simple optical setups and experimental approaches to measure physical quantities of light (e.g. the wavelength)
  • To embark on and pursue research of the highest quality in waves and optical physics
