UNIT 1 ELECTROMAGNETIC RADIATION Radiation
Electromagnetic UNIT 1 ELECTROMAGNETIC RADIATION Radiation Structure 1.1 Introduction Objectives 1.2 What is Electromagnetic Radiation? Wave Mechanical Model of Electromagnetic Radiation Quantum Model of Electromagnetic Radiation 1.3 Consequences of Wave Nature of Electromagnetic Radiation Interference Diffraction Transmission Refraction Reflection Scattering Polarisation 1.4 Interaction of EM Radiation with Matter Absorption Emission Raman Scattering 1.5 Summary 1.6 Terminal Questions 1.7 Answers 1.1 INTRODUCTION You would surely have seen a beautiful rainbow showing seven different colours during the rainy season. You know that this colourful spectrum is due to the separation or dispersion of the white light into its constituent parts by the rain drops. The rainbow spectrum is just a minute part of a much larger continuum of the radiations that come from the sun. These are called electromagnetic radiations and the continuum of the electromagnetic radiations is called the electromagnetic spectrum. In the first unit of this course you would learn about the electromagnetic radiation in terms of its nature, characteristics and properties. Spectroscopy is the study of interaction of electromagnetic radiation with matter. We would discuss the ways in which different types of electromagnetic radiation interact with matter and also the types of spectra that result as a consequence of the interaction. In the next unit you would learn about ultraviolet-visible spectroscopy ‒ a consequence of interaction of electromagnetic radiation in the ultraviolet-visible -

A Comparative Study of Jadeite, Omphacite and Kosmochlor Jades from Myanmar, and Suggestions for a Practical Nomenclature
Feature Article A Comparative Study of Jadeite, Omphacite and Kosmochlor Jades from Myanmar, and Suggestions for a Practical Nomenclature Leander Franz, Tay Thye Sun, Henry A. Hänni, Christian de Capitani, Theerapongs Thanasuthipitak and Wilawan Atichat Jadeitite boulders from north-central Myanmar show a wide variability in texture and mineral content. This study gives an overview of the petrography of these rocks, and classiies them into ive different types: (1) jadeitites with kosmochlor and clinoamphibole, (2) jadeitites with clinoamphibole, (3) albite-bearing jadeitites, (4) almost pure jadeitites and (5) omphacitites. Their textures indicate that some of the assemblages formed syn-tectonically while those samples with decussate textures show no indication of a tectonic overprint. Backscattered electron images and electron microprobe analyses highlight the variable mineral chemistry of the samples. Their extensive chemical and textural inhomogeneity renders a classiication by common gemmological methods rather dificult. Although a deinitive classiication of such rocks is only possible using thin-section analysis, we demonstrate that a fast and non-destructive identiication as jadeite jade, kosmochlor jade or omphacite jade is possible using Raman and infrared spectroscopy, which gave results that were in accord with the microprobe analyses. Furthermore, current classiication schemes for jadeitites are reviewed.

General Workshop
CARPENTRY INTRODUCTION Wood is an important engineering material that is extensively used in the buildings and industries. ‘Timber’ is another name for wood, which is obtained from exogeneous trees. “Wood Working” means processing of wood by hand and machines for making articles of different shapes and sizes. It is further divided into two groups; (1) Carpentry (2) Pattern making. Carpentry is the common term used with any class of work with wood. Pattern making deals with the type and construction of wooden patterns. Steel Rule Four fold rule Flexible tape Blade Try square Stock List of Tools I. Marking and Measuring tools 1. Pencil 9.
