Optics is the study of light and its properties. It is a branch of physics that deals with the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. The term 'optics' can refer to the behavior of visible, ultraviolet, and infrared light. The solutions for the term OPTICS are FIBER (5 letters), VISION (6 letters), EYE (3 letters), and PRISM (5 letters). Fiber optics is the technology of transmitting light through optical fibers for communication and sensing. VISION is the ability to see, which is made possible by the EYE. The EYE is an organ that detects light and converts it into signals sent to the brain. A PRISM is a transparent optical element with flat, polished surfaces that refract light.
