Answer to Question #323052 in Optics for Chemomed

Question

What is optics?

Answer 1

Optics is a branch of physics that is dedicated to the study of visible light : its properties and behavior. It also analyzes its possible applications in the life of the human being , such as the construction of instruments to detect or use it.

Light has been defined by optics as a strip of electromagnetic emissions , whose behavior is similar to other invisible (for us) forms of the electromagnetic spectrum , such as ultraviolet or infrared radiation.

This means that their behavior can be described according to wave mechanics (except in very specific contexts in which light acts as a particle) and the classical electrodynamic approaches of light.

Optics is a very important field of research that nourishes other sciences with tools , especially astronomy , engineering, photography and medicine (ophthalmology and optometry). To it we owe the existence of mirrors, lenses, telescopes, microscopes , lasers and fiber optic systems.
