Optics

Ancient Greek ὀπτική - appearance or appearance) is a branch of physics that describes the interaction of light with the behavior, properties and objects of light. Illuminism explains the phenomenon of optical light.

Observatories generally describe the behavior of visible, infrared, and retinal light; Since light is also an electromagnetic wave, similar phenomena such as dyeing rays, microwaves, radio waves, and other forms of electro-magnetic radiation. So, optics can be considered as a branch of electromagnetic theory. The direct phenomena of some photons relies on quantum nature, which also adds optics to quantum mechanics. In reality, a large number of photographic phenomena can be explained by Maxwell's equation using electromagnetism of light.

Nimrud lenses, which are currently located in the British Museum.
Photochemistry began with the advancement of lenses by ancient Egyptians and Mesopotamians. The earliest lenses that were known were polished crystals, often quartz [1] (about 700 AD), popularly known as the Eshiro-Deshi Lyarad / Nimrud Lens. The ancient Greeks and Romans used to make lenses filled with glass spheres. These practical developments are followed by the theoretical progression of light and vision of Greek and Indian philosophers, and by improving geometric optics of Greco-Roman. The word "light" comes from the ancient Greek word ὀπτική, which means "the appearance, the scene". [2]

Plato first published the theory of emission of light, according to him the philosophy was realized by light emitted from the eyes. He commented on the opposite parallelism of Timus' mirror. [3] About hundred years later, Euclid wrote a book called Optics. In this book, he established geometry with geometry and created geometrical optics. [4] He continued his work based on Plato's emission theory, where he described the mathematical rules of optics and the qualitative interpretation of the reflection of light, though no one ever winked at the eye If he looks, then how can a star be brightened immediately by the light of his eyes? Rasnera was encountered. [5] Ptolemy, in his treatise in optics, said the theory of an exit-emission vision: eye ray (or flask) to form a cone, whose top floor of the eye and the visual field. The rays were sensitive and transported information to the observer about the distance and direction of the surface. He took many summaries of Euclid's work and found a way to measure the refractive angle, though he failed to see the relation between the angina and the rectangle angle. [6]
