Optical sciences is a branch of physical science that focuses on the study of light and its interactions with matter. It encompasses the study of phenomena such as reflection, refraction, diffraction, polarization, and interference. Optical sciences are applied in a wide range of fields, including physics, engineering, biology, medicine, and telecommunications. Research in optical sciences often involves the development of new optical materials, devices, and systems to advance technologies such as lasers, telecommunication networks, imaging systems, and sensors.
