FIRST SEMESTER 2023-2024
Course Handout (Part II)
Date: 12.08.2023
Course No.: PHY F213
Course Title: Optics
Instructor-in-charge: Teny Theresa John
Office: D320/11
Course Description:
This course covers different optical phenomena and the techniques used to study them,
assuming a basic knowledge of optics and electromagnetic waves.
Scope and Objectives of the Course:
The objective of this course is to look at ‘light’ from different perspectives i.e., geometrical,
wave, electromagnetic and particle to explain the observed optical phenomenon like
Interference, Diffraction, Polarization, Photoelectric effect etc. The advanced topics of
Laser theory and some laser systems also will be discussed.
