Diffraction Grating Lab 11

Possible Sources of Error:

1) Select this If measurements are used,
Most measurements require you to estimate one significant figure. This estimation is frequently different if done repeatedly, especially if done by different people, and introduces "random error".
Systematic error will come from an error in your measuring apparatus. Maybe your vernier is not zeroed. Maybe the diffraction grating is cheap and the lines/cm is not accurate, etc.So every measurement will be in error because of inaccurate instruments 2) Misreading the vernier scale. Not seeing the maximum left angle or right angle spectra, thus the average angle calculation doesn't match with the right wavelength for mercury. Difficulty in seeing the lines through the telescope. 3) Error in the number of slits per meter: the error in slit width is what causes the error in the number of slits per metre, so the proportional errors are the same. 4) Distance between light source and the surface
Size of the light source
Attenuation as it passes through air 5) If The measurement of the grating constant from relection off the meter scale was slightly more error-prone use this: Factors that might account for the error are irregularities in the grating, mistakes in the calibration, or similar systematic flaws.

In this section you can include general statements saying: * Whether your measurements confirm the stated objectives. * What fundamental physical laws were illustrated by the experiment * How the experimental error could have been reduced in the experiment.
Also include a constructive critique of the lab, stating what went well, what didn’t, and how the laboratory could be improved.
Error Analysis Questions
How was  related to the angle of diffraction? How is  related to the color of the line? Was the wavelength of a particular

Chm 101

...CHM 1101 Introductory Chemistry Dawn Fox Medeba Uzzi August, 2007 Compiled and edited by Medeba Uzzi Authors’ Note This document is an initiative by the authors in an attempt to deal with what they think may be one of the reasons contributing to the relatively high failure rate in the introductory Chemistry course (CHM 1101) at the University of Guyana. It was brought to our attention that many first year students taking CHM 1101 are unable to efficiently cope with the frenetic pace of the Semester system and even less able to deal comprehensively with the large content in CHM 1101. It is hoped that by providing this paper, students will not need to make lots of notes in lectures and so they can focus on grasping the concepts taught. The document is meant to be a guide to the topics covered in CHM 1101 and is by no means exhaustive. Students are still required to attend classes regularly and punctually and to engage meaningfully in lectures and tutorials. Further, supplemental reading of these topics in any good General Chemistry text is expected. Dawn Fox Medeba Uzzi 2 SECTION 1 – Modules A – D: section deals with the foundation for chemistry. It introduces students to matter & its classification, Atom & its structure, Periodic table and chemical rxns. Introduction to Science and Measurement What is Chemistry? – Chemistry is the study of matter and its transformations Natural sciences refer to the systematic study of the natural world (our...

...France is actively involved, is to prepare the future nuclear sector in an international framework by jointly developing the R&D of 4th generation reactors, based on clearly identified objectives: achieve sustainable development of nuclear energy by optimising the use of natural uranium resources and by reaching the highest levels of nuclear safety; minimise the production of the most radioactive waste, in particular long-lived waste; ensure high resistance to nuclear proliferation; develop applications of nuclear energy for other uses than production of electricity. After an analysis phase carried out jointly by the founding partners, the GIF selected six concepts of nuclear reactors and their cycles4 which exhibited the most promising potentials to achieve the abovementioned objectives: SFR: Sodium-cooled Fast Reactor; GFR: Gas-cooled Fast Reactor; LFR: Lead-cooled Fast Reactor; SCWR: Supercritical Water-cooled Reactor; VHTR: Very High Temperature Reactor; MSR: Molten Salt Reactor. Except for the VHTR, all these systems operate in closed cycle, that is to say that they are based on recycling of reusable materials, in particular plutonium. The first three systems among the six ones are characterised by the fact that they are fast neutron reactors (FR). These are the SFR, GFR and LFR systems which...

Hsc Chemistry Notes

...Chemistry Notes 2010 Core Module 1: Production of Materials Contextual Outline Humans have always exploited their natural environment for all their needs including food, clothing and shelter. As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments. Added to this was a reduction in availability of the traditional resources to supply the increasing world population. Chemists and chemical engineers continue to play a pivotal role in the search for new sources of traditional materials such as those from the petrochemical industry. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. In addition, chemists are continually searching for compounds to be used in the design and production of new materials to replace those that have been deemed no longer satisfactory for needs. This module increases students’ understanding of the implications of chemistry for society and the environment and the current issues, research and developments in chemistry. 1.1 Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: • Acid reactions: o acid (aq) + base (aq)  salt (aq) + water (l) o acid (aq) + active metal (s)  salt (aq) + hydrogen (g)...
