1 Unit – 4 Engineering Physics OPTICS Dr. V.P.N. Padmanaban M.Sc.‚ Ph.D.‚ Associate Professor 1. Interference Interference of light waves is a superposition phenomenon. This phenomenon was first described by Thomas Young in 1801. It provided strong evidence for the wave theory of light. In Young’s interference experiment‚ an incident monochromatic light is diffracted by a slit in the first screen‚ which then acts as a point source of light that emits semicircular wavefronts. It is

Jelly Optics Investigatory Project in Physics Chapter 1 The Problem and its Background Introduction When light hits a boundary between two substances‚ it often bends. This is called refraction. Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. Refraction is responsible for image formation by lenses

PC1222 Fundamentals of Physics II Tutorial 8 1. Refraction of Light I. When a man stands near the edge of an empty drainage ditch of depth 2.80 m‚ he can barely see the boundary between the opposite wall and bottom of the ditch as shown. The distance from his eyes to the ground is 1.85 m. (a) What is the horizontal distance d from the man to the edge of the drainage ditch? (b) After the drainage ditch is filled with water as shown‚ what is the maximum distance x the man can stand from the edge

Dispersion: The speed of light is slower in various materials than it is in a vacuum or outer space. When the light passes into a material at an angle‚ the light beam is bent or refracted according to Snell’s Law and the index of refraction of the material. But also‚ the speed of light through a material varies slightly with the wavelength or frequency of the light. Thus‚ each wavelength is refracted at a slightly different angle when passing through a material at an angle. This spreading out of

military/aerospace platform operational environment challenges the creativity of fiber optic module packaging engineers as they endeavor to develop and mature new active and passive single-mode fiber optic and photonic components for next generation avionics networking applications. Low sales and manufacturing volumes inherent to avionics combined with lack of standard interface specifications for current and next generation fiber optic local area network architectures and sub-systems makes it difficult for avionics

of high quality and high-speed telecommunication systems. Today‚ optical fibers are not only used in telecommunication links but also used in the Internet and Local area networks (LAN) to achieve high signaling rates. What is fiber optic communication? Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. Electrical signal
