Yes, but keep in mind the mathematical equations might be slightly grainy in scanned versions. If you are serious about physics, I recommend the physical book because flipping back and forth between the theory and the solved examples is easier in print than in a PDF.
This section treats light as rays traveling in straight lines. It forms the foundation for designing optical instruments. If you are serious about physics, I recommend
by and Brij Lal has been a cornerstone for undergraduate physics students across India and beyond. Known for its clarity and systematic approach, this seminal work—often updated by M.N. Avadhanulu —is essential for anyone mastering classical and modern optical phenomena. Why This Book is a Student Favorite
Trust me—when you are preparing for exams, the last thing you want is to discover that your "verified" PDF is missing the crucial derivation of Newton’s Rings or the resolving power of a grating. by and Brij Lal has been a cornerstone
