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

Google Fiber Adam Fleiner NT1110 Friday 6pm Moran Google Fiber is a revolutionary internet and television service. This service could change the way people use internet and watch television drastically. It is only available in a small number of cities as of now; however the company is working on spreading at a steady pace. As of now the total number of cities that may have this service soon is 34. By the end of this year there will be another list of cities to receive this service. Other cable

Descartes Optics Descartes’s theories of light and vision were central components of his natural philosophy‚ closely linked to his cosmology‚ physics‚ theory of matter‚ and theory of perception. Descartes replaced traditional explanations of natural phenomena with explanations hidden under terms of matter and motion. By eliminating these theories‚ Descartes needed to formulate new explanations of the qualities of bodies and our perception of them. In other words Descartes goes on to call into

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
