B.Sc. Practical Physics C.L. Arora , published by S. Chand Publishing , is a foundational textbook designed to align with the UGC Model Curriculum National Education Policy (NEP) 2020
In the summer of 2021, when university campuses were cautiously reopening and students craved hands-on lab time after long virtual semesters, a battered copy of C.L. Arora’s B.Sc. Practical Physics made its way into the quietest corner of the college physics lab. Its spine bore the marks of many semesters; inside, typed tables, penciled corrections, and coffee-ringed pages told stories of experiments repeated until concepts felt like second nature. b sc practical physics cl arora 2021

Despite its merits, the 2021 edition reveals a conspicuous . By 2021, many physics departments had begun incorporating Arduino-based sensors, Python-based data fitting (using SciPy or Matplotlib), and virtual labs (e.g., PhET simulations). Arora’s book, however, still relies on manual graph plotting on millimeter paper, calculation using log tables or basic calculators, and error analysis by the maximum possible error method. There is no mention of least-squares fitting using software, no discussion of uncertainty propagation using Monte Carlo methods, and no guidance on interfacing sensors with computers.
