This book takes the reader on a smooth journey through classical and modern physics concepts that are deeply connected to real-world technology. It begins by explaining how electric charges behave and interact, then moves on to how energy is stored, transferred, and used in electrical systems. Gradually, the focus shifts to magnetism and how electricity and magnetism are linked together, leading to ideas that explain motors, generators, and power transmission.
As the book progresses, it introduces light and waves, explaining how we see objects, how lenses work, and why interference and diffraction occur. The later sections step into modern physics, where the behavior of matter and radiation is discussed at atomic and nuclear levels. Finally, the book connects theory to practice by explaining semiconductors and electronic components that form the base of today’s digital devices. Overall, the content balances theory, numerical problems, and conceptual clarity, making complex ideas easier to grasp.
