INTRODUCTION A mirror is an object that reflects light or sound in a way that preserves much of its original quality prior to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are

produced by the acceleration of an electric charge. Refeaction: a return of electromagnetic energy. Medium: when referring to Ethernet LANS the transceiver in the Ethernet networks. Total internal reflection: the reflection in a medium of a given refractive index. Fresnel reflection: reflection of a small amount of light passing from a medium of one reflective index into a medium of a different index. Tensile strength: resistance to pulling or stretching forces. Dispersion: a spreading of light

no longer) labour-intensive process. Fibre Optic Bundles If light enters the end of a solid glass rod so that the light transmitted into the rod strikes the side of the rod at an angle O, exceeding the critical angle, then total internal reflection occurs. The light continues to be internally reflected back and forth in its passage along the rod, and it emerges from the other end with very little loss of intensity. This is

Unit 7.Exercise 1. Fiber Optics--Definitions Cross Talk- Fiber-optic cabling is immune to crosstalk because optical fiber does not conduct electricity and uses light signals in a glass fiber, rather than electrical signals along a metallic conductor, to transmit data. So it cannot produce a magnetic field and thus is immune to EMI. Waveguides- A structure that guides electro-magnetic waves along their length. The core fiber in an optical fiber cable is an optical waveguide FTTH- Fiber to the

than the water inside the glass. Refraction of light is bending of light as it enters medium of different density. Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear

Experiment 9: Reflection, Refraction, and Total Internal Reflection Purpose: The purpose of this experiment was to study the laws of reflection, refraction and total internal reflection, to measure the focal length of mirrors with convex and concave mirrors, and to measure the index of refraction of water. Theory: In this experiment, we learned that the angle of incidence θi is the angle that the incident ray makes in regards to the normal one. Also, the angle of reflection θr is the angle

Chapter 15: Refraction and Lenses Refraction of Light If water waves in a ripple tank travel from water with a depth of 1 cm into a shallow area with a depth of .3 cm, the water will slow down. In a ripple tank the depth can be changed by placing a sheet of plexiglass or glass in the water. In the picture to the right the area to the left is deeper water and the the the right is shollow. The picture shows that when the water travels into a shallow area and slows down, the wavelength will
