What is optical physics?

Optical physics is a branch of physics that focuses on the study of light, including its generation, transmission, detection, and interaction with matter. It encompasses the behavior and properties of light, such as reflection, refraction, diffraction, and polarization, as well as the development and application of optical instruments like lenses, lasers, and fiber optics. Optical physicists work in a variety of fields, including telecommunications, imaging, medical technology, and quantum computing, to develop new technologies and improve our understanding of light.
