Optics is a field of science that deals with the behavior of light, sight, and radiation. It is a branch of physics and can also describe reflections and refractions. Etymologically, optics is the study of vision. Light waves are electromagnetic waves - they consist of mutually perpendicular electric fields and magnetic fields, and can travel through a vacuum. Optics is the study of electromagnetic waves in general. So it covers all waves in the electromagnetic spectrum given below:
One of the most controversial questions in optics is whether light is a wave or a ray. Accordingly, there are two branches of optics, but only ray optics belongs to classical physics. Wave optics are a topic of modern physics. In ray, optics covers topics such as reflection and refraction and the dispersion of white light into its constituent colors. This article is a stub.
