Breaks down the mathematical boundaries between near-field (Fresnel) and far-field (Fraunhofer) diffraction using zone plates and grating equations.
The textbook is divided into major sections that transition from classical ray optics to advanced modern photonics: Geometrical (Ray) Optics
If the PDF does not contain the chapter on Holography or Non-Linear Optics , it is likely a very old (pre-2010) edition. The "UPD" version is usually the Revised Edition 2018 or later .

by N. Subrahmanyam and Brij Lal is a foundational resource for undergraduate physics students, specifically designed to meet the UGC Model Syllabus . The book covers 26 chapters across three main divisions: Ray (Geometrical) Optics , Wave (Physical) Optics , and Quantum/Modern Optics . Detailed Table of Contents Wave (Physical) Optics
Be cautious of suspicious third-party blogs or compressed "download zip" loops, as they often host outdated formats or malware. For verified digital learning, the textbook can be previewed or legally acquired on platforms like Google Books or purchased as a Kindle edition via Amazon .
This portion shifts away from rays to treat light as an electromagnetic wave, explaining phenomena that ray optics cannot.
