Definition of optics

The word "optics" has its roots in the Greek word "optikos", which means "sight" or "vision". This term was first used in the 14th century to describe the study of the properties and behavior of light. The Greek philosopher Euclid wrote extensively on optics in his book "Optica", which explored the way light interacts with matter. In the 17th century, the term "optics" became more widely used to describe the scientific study of light and its applications. Sir Isaac Newton's work on optics, published in his book "Opticks", further solidified the term's place in the scientific community. Today, optics encompasses a broad range of fields, from the study of the behavior of light to the development of optical fibers and lenses. Despite its evolution, the word "optics" remains rooted in its ancient Greek origins, reflecting its continued connection to the fundamental concept of sight and vision.
