## Full Description
If you are a Class 12 student who has ever felt lost staring at a derivation or a numerical that just would not click, this book was written for you. S.L. Arora's New Simplified Physics Volume 2 does not assume you already know everything — it walks you through each concept step by step, anticipates your doubts, and answers them before you even finish the question. By the time you close this book before your board exam, you will have worked through clear theory, solved examples, conceptual questions, HOTS problems, and previous-year board questions — all in one place.

Volume 2 picks up where Volume 1 leaves off and covers the second half of the CBSE Class 12 Physics syllabus in full. The chapters covered are: Electromagnetic Waves (Maxwell's equations, the EM spectrum, properties and uses of radio waves, microwaves, infrared, UV, X-rays, and gamma rays); Ray Optics and Optical Instruments (reflection, refraction, lenses, mirrors, total internal reflection, optical fibres, prisms, microscopes, telescopes); Wave Optics (Huygens' principle, interference, Young's double slit experiment, diffraction, polarisation, Doppler effect of light); Dual Nature of Radiation and Matter (photoelectric effect, Einstein's equation, de Broglie's wave-particle duality, Davisson-Germer experiment); Atoms (Rutherford and Bohr models, hydrogen spectrum, spectral series); Nuclei (nuclear forces, binding energy, radioactivity, nuclear fission and fusion, nuclear reactor); Semiconductor Devices and Digital Circuits (p-n junction, diodes, transistors, logic gates, Boolean algebra); Communication Systems (modulation, bandwidth, propagation of EM waves, satellite communication, internet and mobile telephony); and Alternating Current and Electrical Machines (AC generator, transformer, RMS and peak values, LC and LCR circuits, resonance, power factor).

Each chapter follows a consistent format: a quick concept map at the start, then theory written in plain English with worked examples woven right into the explanation. After the theory, you get a tiered question bank — very short answer, short answer, long answer, numerical problems, HOTS, and value-based questions. This structure makes revision fast and systematic, especially in the weeks before boards.

Who is this book for? Primarily Class 12 CBSE students aiming for high scores in board exams. But it is equally useful for students preparing for JEE Main — the theory and problem variety here are strong enough that many coaching teachers use it as a supplement to build conceptual clarity before moving to harder JEE-level problems. NEET aspirants will find the modern physics chapters (Atoms, Nuclei, Dual Nature, Semiconductors) particularly useful, as these directly overlap with NEET's physics section. Students appearing for NDA written exams also benefit since Physics is a tested subject there. For state board students whose syllabus mirrors CBSE, this book works perfectly as a reference guide.

S.L. Arora has been writing physics books for Indian students for decades. He is the author of Move Fast With Physics for Class 11, Pictorial Dictionary of Science, Dictionary of Science and Technology, and several science project books published by Dhanpat Rai & Co. His writing style has one distinguishing quality — he writes the way a good teacher explains in class, not the way a textbook reads. Students consistently mention that his derivations are the easiest to follow among all reference books available for Class 12 Physics.

Dhanpat Rai & Co., the publisher, is one of India's oldest and most respected educational publishers, known for producing books that stay closely aligned with NCERT and CBSE guidelines. The book is updated annually, so the edition you download here matches the current board syllabus and exam pattern.

This PDF is optimised for mobile reading — compressed without quality loss so it loads quickly even on slower connections. Whether you are reading on your phone during a commute or on a laptop late at night, the layout holds up cleanly. No broken formatting, no missing pages.

If your board exam is coming up and you want one book that covers everything — theory, numericals, previous year questions, and quick-revision tools — this is it. Download, start with whichever chapter your teacher is on right now, and work through it consistently. That is all it takes.
