<p>Applied physics is rooted in the fundamental truths and basic concepts of the physical sciences but is concerned with the utilisation of these scientific principles in practical devices and systems. Applied physicists can also be interested in the use of physics for scientific research. This book dwells on subjects like crystal structures semiconductors electrostatic force optics of light quantum mechanics geometric optics electromagnetic radiation light amplification by stimulated emission of radiation etc.</p><p>What is crystallography? What is the significance of Latice Points? What is the defining property of a crystal? How many crystal classes exist? What is Coulomb’s Law? What is its relevance in electrostatic force? Can light be classified as a force of energy or as a wave or as a particle? Who was the first person to give a full explanation of how a rainbow is formed? What are the properties of a shadow? What is the ‘principle of superposition’? Who was Christiaan Huygens? What was the important insight he shared with the world? What is a spring pendulum? What is the word ‘laser’ an acronym for? What are the different types of lasers? The book answers all the above questions and more.</p>
