Jun 21, 2021 · Free Space Optics (FSO) is an optical communication technique which disseminates light in free space such as air, vacuum or celestial space, to wirelessly transfer data. The bigger the mirrors or lenses, the more light the telescope can gather. Newton’s experiments demonstrated that all the colors already existed in the light in a heterogeneous fashion, and that “corpuscles” (particles) of light were fanned out because particles with different colors traveled with different speeds through the prism. In 1905, nearly a decade after this first "thought experiment," Einstein answered these questions with his Special Theory of Relativity. As light enters the gelatin, the change in medium causes a change in the speed of the light and a change in the index of refraction.

Jan 29, 2021 · Nature Photonics spoke to Aydogan Ozcan about the rise of artificial intelligence-enabled optics and the hurdles ahead. Light can travel through these fibers over long distances. The optics of a telescope must be almost perfect. Because the fibers are thin, light entering one is likely to strike the inside surface at an angle Goal: Where Will the Light Go? Although simple lenses are often used in imaging applications, in many cases their goal is to project light from one point to another within a system. In everyday speech, the word "light" often means visible light, which is the type the human eye can see. For a converging lens, the focal point is where the converging light rays cross; for a diverging lens, the focal point is the point from which the diverging light rays appear to originate. In other words, optics explains the behaviour of infrared, visible and ultraviolet light. You will do basic study of optics in your physics class, but in general only electrical engineers will delve into the topic more thoroughly (and if you want to go really in-depth then you need to study graduate physicists).
