The term ‘light’ refers to a form of electromagnetic radiation that enables the human eye to see or make things visible. An interesting consequence of this is that a light ray will change direction when passing from one medium to another. Interestingly, not all light phenomena can be explained by Maxwell’s theory. When we talk about light, we usually mean any radiation that we can see. 4. The part of optics dealing with the ray aspect of light is called geometric optics. In other ways, light behaves much more like a stream of particles—like bullets firing in rapid succession from a gun. Smith, M. Today Optics remains a key element of modern science, not only as an enabling technology, but in Quantum Optics, as a means of testing our fundamental understanding of Quantum Theory and the nature of reality itself. When light propagates in a transparent material medium, its speed is in general less than the speed in vacuum c. ×= ×89fej−, so the frequency is 4741.
