 # A Textbook of Engineering Physics Practical

The basic fundamental Physics forms the foundation of engineering and technology. Physics, and natural science (being a description of the nature around us) in general, is a reasonable enterprise based on valid experimental evidence, criticism, and rational discussion. It provides us with knowledge of the physical world, and it is an experiment that provides the evidence that grounds this knowledge. Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. Experiment can provide hints toward the structure or mathematical form of a theory and it can provide evidence for the existence of the entities involved in our theories.

This book grew out of the lectures delivered in theory and practical classes by us to the students at the Bhilai Institute of Technology, Durg (Chhattisgarh). Along with the CSV Technical University practical syllabus, the book attempts to give a comprehensive account of a large number of other important experiments in engineering physics as well.

This book has been written with the specific aim of presenting the subject-matter in the simplest possible manner keeping in view the difficulties and the limitations of the average students. The completely redesigned, pedagogically consistent artwork and diagrams integrate seamlessly with the text to help "more visual" learners better visualize key concepts. The difficult experiment are explained in a simple language with the help of neat diagrams. We feel that if a student does all these thoroughly, the subject will appear to be friendly and enjoyable.
