Elements of Modern Physics: (As per UGC-CBCS Curriculum)

This textbook has been designed as per the UGC Choice Based Credit System (CBCS) curriculum to meet the requirements of undergraduate students of physics. It extensively covers the fundamental principles, synthesis and physical interpretation of atomic physics, quantum mechanics, nuclear physics and lasers. Laboratory work has also been included to help students achieve solid conceptual understanding and learn experimental procedures.

·         14 lab experiments to help students make observations, develop hypotheses about phenomena and devise tests to investigate their hypotheses

·         More than 275 well-labelled diagrams for easy understanding of the concepts

·         Over 175 chapter-end questions to enhance and strengthen learning of the students

·         Additional Roadmap for the syllabuses of Odisha State, Calcutta, Gauhati, Dibrugarh and Burdwan universities
