    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...

    What is Fiber Optics? What is Fiber Optics? Fiber optic cable in essence, is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed. In case you are wondering why light traveling through fiber optic cable does not actually travel at true light speed, it is because the glass that makes up fiber optic cable is denser than the vacuum of outer space where light can travel without disruption. Needless to say, a fiber optic light signal is still...

    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...

    Baldeo Persaud NT1310 Unit 7 Assignment 1: Refraction, Reflection and Optics A good example of refraction of light and reflection of light is a rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle, which is the angle the sunlight strikes the back of the rain droplet. Red light bends the...

  • Dispersion and Its Types in Fiber Optics
    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...

    Week 7, Unit 7. Assignment 1. Reflection, Refraction and Optics Refraction is the bending of waves as they pass from one medium to another, due to a change in their speed. The phenomenon is most commonly associated with light, but can also apply to sound, or even water, waves. It happens when a series of waves travels toward the new medium at an angle, so that one side experiences a change in speed before the other, causing it to turn toward the slower side in the same way that a moving...

    Refraction in Biconcave Lens Now let's investigate the refraction of light by double concave lens. Suppose that several rays of light approach the lens; and suppose that these rays of light are travelling parallel to the principal axis. Upon reaching the front face of the lens, each ray of light will refract towards the normal to the surface. At this boundary, the light ray is passing from air into a more dense medium (usually plastic or glass). Since the light ray is passing from a medium in...

    Mirror - is an object that reflects light in a way that preserves much of its original quality subsequent to its contact with the mirror. Plane mirror - plane mirror is a mirror with a planar reflective surface. Concave mirror - A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point, therefore they are used to focus light. Convex mirror reflection - A convex mirror,...

  • Optical Properties of Quasicrystals: Negative Refraction
    Optical Properties of Quasicrystals: Negative Refraction Quasicrystals, or crystals that display the unusual property of non-periodicity (while remaining ordered), were discovered in the 1980s by Dan Shechtman. A highly controversial topic, Shechtman did not produce a paper describing them for over two years after their discovery. However, within the past 30 years, the scientific community has come to accept them, reproduce them for study, and even award Dan Shechtman with a Nobel Prize for...

In particular, the number of propagable waves and the optimal shape of the refractive index profile will be discussed. The single-mode step-index fiber has a high bandwidth (essentially limited only by the waveguide dispersion and material), but has, due to the generally small fiber parameter V , either a small core diameter or a small numerical aperture. This leads to problems with linking...
