Applied Physics (Part – II) is designed as a continuation of Applied Physics (Part – I) to meet the academic requirements of undergraduate students. The book covers three important units—Hydrostatics and Hydrodynamics, Heat and Light, and Electricity and Magnetism—in a systematic and student-friendly manner. The content aims to provide strong conceptual understanding while remaining aligned with prescribed academic syllabi.

The first unit, Hydrostatics and Hydrodynamics, introduces the principles governing fluids at rest and in motion. Topics include Pascal’s law, Archimedes’ principle, Bernoulli’s principle, laws of floatation, centre of buoyancy, stability of floating bodies, metacentric height, hydrostatic pressure, surface tension, capillarity, and viscosity. Experimental methods such as Stoke’s method and Poiseuille’s flow method are also discussed to connect theoretical principles with practical applications.

The second unit, Heat and Light, focuses on thermodynamic laws, gas laws, specific heat capacities, and heat transfer processes including conduction, convection, and radiation. Experimental methods and applications such as Lee’s disc method and black body radiation are included. The unit further explains reflection, refraction, interference, diffraction, polarization, and optical instruments including the compound microscope and resolving power.

The third unit, Electricity and Magnetism, explains electric current, resistance, circuit laws, magnetic effects of current, electromagnetic induction, generators, and transformers. Concepts such as Kirchhoff’s laws, Wheatstone’s bridge, self and mutual induction, and transformer efficiency are discussed with practical relevance.

This book aims to bridge theoretical understanding with practical applications and is expected to serve as a valuable academic resource for undergraduate students and educators.
