Physics, at its core, is the study of nature and the laws that govern the physical world. While theoretical understanding builds the foundation of physics, it is through practical experimentation that students truly appreciate the principles at work. Fundamentals of Practical Physics for Class 11 (HS 1st Year) is designed to bridge this essential connection between theory and practice, enabling students to cultivate both analytical skills and a spirit of scientific inquiry.

Authored by a team of dedicated educators — Dr. Anup Kumar Nath, Dr. Smritimala Sarmah, Dr. Rajesh Verma, Dr. Jibon Saikia, and Mr. Rajen Dutta — and published by Mahaveer Publications, Dibrugarh, this book offers a comprehensive and methodical approach to practical physics. Drawing upon years of academic experience, the authors have meticulously crafted experiments and activities that are aligned with the latest curriculum requirements, ensuring relevance and clarity for Higher Secondary (HS) First Year students.

This book emphasizes:

• Clear explanations of experimental principles.

• Step-by-step procedures for performing experiments accurately.

• Proper methods of data recording, calculation, and analysis.

• Guidelines for drawing appropriate conclusions and understanding sources of error.

• Safety measures to be followed in the laboratory.

Each experiment has been structured to promote logical thinking, careful observation, and precision — key attributes for any aspiring scientist. Special attention has been given to develop students' skills in measurement, data interpretation, and scientific reporting, which are crucial for higher studies and professional research.

We hope that this book will not only assist students in mastering the essentials of practical physics but also inspire them to explore the fascinating phenomena that define our universe. The authors extend their heartfelt wishes to all learners and teachers who embark on this exciting journey of discovery.
