OPTICAL COMMUNICATION AND NETWORKING 2 Marks Questions and Answers UNIT - 1 - INTRODUCTION 1. Define a fiber optic system. Fiber optic system consists of a fiber optic cable, a light source and a light detector. The optic fiber is used to carry the light beam from one place to another. 2. What are the uses of optical fibers? a) To transmit the information of telephone communication, computer data, etc. which are in the form of coded light signals b) To transmit the optical imag...

Vocabulary: angle of incidence, angle of refraction, frequency, index of refraction, medium, refraction, Snell’s law, total internal reflection, wave front, wavelength, wave speed Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Two runners ran side by side, each holding one end of a horizontal pole. 1. What would most likely happen if one of the runners began jogging in knee-deep water? __________________he would probably slow _____________________________________________...

Physics - Mark scheme instructions to examiners 1. General The mark scheme for each question shows: • the marks available for each part of the question • the total marks available for the question • the typical answer or answers which are expected • extra information to help the Examiner make his or her judgement and help to delineate what is acceptable or not worthy of credit or, in discursive answers, to give an overview of the area in which a mark or marks may be awarded. ...

Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the students’ responses to questions and that every associate understands and applies it in the same correct way. As ...

Unit 1: Optics Chapter 2: Geometric Optics and Image Formation University Physics Volume III Unit 1: Optics Chapter 2: Geometric Optics and Image Formation Conceptual Questions 1. What are the differences between real and virtual images? How can you tell (by looking) whether an image formed by a single lens or mirror is real or virtual? Solution Virtual image cannot be projected on a screen. You cannot distinguish a real image from a virtual image simply by judging from the image perce...
