Quantum theory: Unit 1
Quantum theory in engineering physics refers to the application of quantum mechanics principles to engineering problems and systems. Quantum mechanics, or quantum physics, is a fundamental theory in physics that describes the behavior of matter and energy at very small scales, such as atoms and subatomic particles.

Electronic Materials:- Unit 2
Electronic Materials in engineering physics refer to substances specifically engineered to conduct, insulate, or semiconduct electricity. These materials are fundamental to the design and function of electronic devices and systems, including transistors, capacitors, and integrated circuits. They are categorized based on their electrical conductivity: 1. Conductors: 2. Semiconductors: 3. Insulators

Fibre Optics Communication: Unit :- 4
Fiber Optics Communication in engineering physics refers to a method of transmitting information as light pulses through a fiber optic cable. These cables are composed of a core surrounded by a cladding layer, both made of glass or plastic, with different refractive indices. The core's higher refractive index ensures that light signals are confined within it and propagate over long distances with minimal loss.
