: Practical study of lenses, spectrometers, Newton’s rings, resolving power of gratings, and diffraction.
C. L. Arora’s B. Sc. Practical Physics (2021 edition) remains a valuable procedural encyclopedia for classical physics experiments. Its clarity, systematic observation tables, and error awareness provide a strong foundation for undergraduate laboratory work. However, as a standalone text in 2026, it is outdated in its neglect of digital instrumentation, computational data analysis, and inquiry-based learning. The optimal use of Arora is not as a bible but as a —one layer in a multi-layered lab curriculum that includes modern sensors, open-source programming, and statistical rigor. Instructors who adopt this blended approach will produce graduates who can both read a vernier caliper and fit a model to noisy data—a true 21st-century experimental physicist.

Another tip: The 2021 edition has a new section on "Simulated Experiments" – short descriptions of how certain experiments can be done using PhET simulations. If your college shifted to hybrid labs post-COVID, this is invaluable.
C.L. Arora is not just an author; he is an institution in Indian physics education. Formerly affiliated with the prestigious , Arora has spent decades refining the pedagogy of physics experiments. His writing style is characterized by:
