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 However, as a standalone text in 2026, it is outdated in its neglect of digital instrumentation, computational data analysis, and inquiry-based learning.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.

: Measuring the wavelength of monochromatic light and the refractive index of liquids.
This introductory section establishes foundational experimental techniques. Students learn to handle precision measuring instruments and study the mechanical properties of solids and fluids. Key experiments include:
Optics experiments are notoriously sensitive to alignment and lighting conditions. The textbook excels in providing step-by-step alignment techniques for complex apparatus.
This section builds the foundational skills every physicist needs.
If you’d like, I can summarize the typical experiment structure Arora uses, list commonly covered experiments in the 2021 edition, or provide a sample lab report template based on the book.
