Opticks (Annotated)

Differentiated book- It has a historical context with research of the time-Opticks: or, a treatise of the reflexions, refractions, inflexions and colors of light. Also two treatises of the species and magnitude of curvilinear figures - in Spanish: Óptica: or a treatise on the reflections, refractions, inflections and colors of light - is a book written by Isaac Newton related to Optics. The book begins with a short introduction where he briefly explains the content of the treatise and tests the properties of light with experimental methods. Book One begins with a series of definitions and axioms. In the definitions part, it begins with light ray, refrangibility and reflexibility, angle of incidence, angle of reflection, single light, incidence sinuses, reflection and refraction. In the Axioms part, he describes how light rays behave and describes the properties of the angles already mentioned.An example is "The angle of reflection is equal to the angle of incidence." It also exposes what is known as Snell's law for different cases, such as flat mirror, spherical mirror, flat surface, surface, spherical, lenses and prisms. In addition you can find a simple explanation of how the eye works. The next part of Book One are propositions, which like the title indica, propose theorems and indicate experimental proofs.
