NS 214 - Oscillations, Waves and Optics 

Oscillations, Waves and Optics – Titreşimler, Dalgalar ve Optik –

3 credits. Instructor: Ali Alpar

This is a new  course  for second year FENS students who have not yet declared their major, as well as 3rd and 4th year students. The course is open to registration as NS 214.

This course will provide the basic physics of linear oscillations and waves, and serve as a common interdisciplinary introduction to applications in different areas of science and engineering. It will also be a basic optics course. The mathematical content will supply examples for our Mathematics faculty courses, Linear Algebra and Differential Equations, on a unified physics basis as well as the use of complex numbers and Fourier analysis with examples from the science of linear systems, waves and optics.

The course will serve the needs of the general 2nd year and later FENS student, and will be an important addition for elective courses for the Physics Minor program.  

The course will start from the linear response of systems close to stable equilibrium. The physics and mathematics of linear systems will be studied with examples from different kinds of systems, their oscillations and wave modes. 

Textbook: Crawford- “Waves” - Berkeley Physics Course Vol.III
