Full Description
Meeting the need for a text that explores physics with an emphasis on practical application, Engineering Physics covers basic and advanced principles for undergraduate engineering, physics, and science students. Part 1 discusses fundamental theories such as crystallography and crystal imperfection, thermoelectricity, thermionic-emission, ultrasonic waves, acoustics, and semiconductors. Part 2 covers advanced topics such as thin film interference and diffraction, x-rays, motion of the charged particle in electric and magnetic fields, quantum physics and Schroedinger wave equation, lasers, holography, fiber optics, radioactivity, and superconductivity. The author explains the technical aspects, applications, fundamental principles, and mechanisms of semiconductor devices, transistors, and CROs with energy level diagrams. She discusses crystal structures, different properties of materials, and the reasons why a particular element has a particular structure. Logically structured to make the content progressively more challenging, each section concludes with problems and questions that deepen understanding of the subject.
