For over half a century, "A Textbook of Optics" by N. Subrahmanyam and Brij Lal has been the gold standard for undergraduate physics students across India. First published in the 1960s by S. Chand Publishing, the book has been revised multiple times, most notably with the help of M. N. Avadhanulu. The enduring popularity of this work is highlighted by the fact that there are library records of the book being continuously checked out and used for decades.

If you are a B.Sc. student or preparing for competitive exams like IIT JAM, CSIR NET, or GATE, this book is often considered the "Bible" for Optics at the undergraduate level. For over half a century, "A Textbook of Optics" by N
Dr. Brij Lal and Dr. Subrahmanyam wrote this text to build a generation of physicists. Honor that effort by using a legitimate copy. Your understanding of interference, diffraction, and polarization will be far clearer on a physical page than on a blurry, pirated screenshot. Chand Publishing, the book has been revised multiple
The core strength of Brijlal and Subramanyam lies in its explanation of wave phenomena.
Brijlal & Subramanyam is not the most advanced optics text, nor is it the most rigorous. But for an —especially for self-study or traditional classroom settings—it remains unmatched.
When the book presents a derivation (like the Lens Maker’s Formula), pick up a pen and follow along step-by-step.
