Engineering physics is a bit more advanced version of what you have learned up to 12th grade. In engineering physics, you will come across relativistic mechanics, lasers, optics, fiber optics, holography, wave mechanics, di-electric and magnetic properties of the material, ultrasonic, electromagnetics, superconductivity, nanotechnology, etc.Engineering physics or engineering science refers to the study of the combined disciplines of physics, mathematics, and engineering, particularly computer, nuclear, electrical, electronic, materials, or mechanical engineering. By focusing on the scientific method as a rigorous basis, it seeks ways to apply, design, and develop new solutions in engineering.
