Connectors are mounted on a large Sub-Plate to facilitate access to cables through the VJ. for. 1. st. year Physics . Honours. Course. By . Arnab. . Gangopadhyay. . Light. The . light. , . with which we see, is a small part of the vast spectrum of electro magnetic field.. Interaction of light with matter divided into three regimes.. Geometrical optics. , or . ray optics. , describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction or "instrument", that can be used to predict the path of light.. Up to now we have been studying . geometric optics. . Today we will look at effects related to the . wave nature of light –. . physical optics. polarization. interference. thin film interference. th. -. Century Physics: The Nature of Light. Alan E. Shapiro, University of Minnesota. Light Is Not the Only Fundamental Problem in 17. th. Century Natural Philosophy. Cosmology: structure of the universe. Optics. Reflection:. Light is retransmitted from or “bounces off” an object. Optics. Law of Reflection:. The angle of incidence equals the angle of reflection.. Optics. Refraction. Light “bends” or changes its angle as it moves from one medium to another.. Light travels in a STRAIGHT LINE . ANOTHER WAY TO THINK OF LIGHT. Light leaving the candle travels in all directions, but we only SEE the light that travels in to our Eye-Brain. ANOTHER WAY TO THINK OF . Julian C. Christou, Gemini Observatory.

What is fiber optics. Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable.. LHC & HL-LHC. S. Fartoukh, BE-ABP.
