Focal length of lenses, spectrometer-based experiments (refractive index), interference, diffraction, and polarization.
Practical physics education faces a persistent tension: the need to teach foundational measurement techniques (screw gauge, vernier caliper, potentiometer, spectrometer) versus the rapid advancement of digital sensors, automated data logging, and computational analysis. C. L. Arora’s B. Sc. Practical Physics first appeared decades ago but continues through revised editions—the 2021 edition being the most recent. Its longevity suggests enduring value, but also raises questions: Does it prepare students for 21st-century experimental physics? How should instructors use it effectively? b sc practical physics cl arora 2021
