The books have a lot of solved problems that are quite practical in life to show applicability of the subjects discussed. In addition, there are a number of practice problems at the end of each chapter. These can easily be tackled by the students after studying the topics in each chapter. In most cases, answers are given to assist the learners in testing their comprehension. The topics covered by these books are carefully selected to suit the universal requirements for the first two years of study of Physics in the Universities. The books can also serve as good reference materials for advanced Physics students to refresh and build up concepts of Physics. They are handy to the University lecturers of Physics as reference materials, and for designing test problems to train learners at various stages.
