At its core, optics refers to the scientific study of light and vision. However, in a broader sense, particularly relevant to IELTS, optics also denotes the way in which an event or course of action is perceived by the public.
Word history: The term optics originates from the Greek word optikos, meaning of or related to sight.
It entered the English language in the early 17th century, initially referring solely to the science of light and vision.
