1 Lab Assignment #5 Write-Up 2 General Info: Name: Date: Purpose: Of Exp #5: In this experiment we will learn about the spectroscope and how it works. To learn the concept of quantitative measurements, to construct a spectroscope and, to use it for taking quantitative measurements. Experimental Questions: Please complete this section of your write-up as you work on the experimental portion of this lab. 1. Hold the grating several inches from your face, at an angle. Look at the grating that you will be using. Describe what you see at the grating surface. I see different color of the rainbow and when I change the angle that am holding the diffraction grating Hold the grating up to your eye and look through it.

All in all, the objectives of the study were met.  INTRODUCTION ​The analytical balance is a fundamental measuring device for all types of quantitative work in analytical chemistry. It is designed for great precision in quantitative chemical analysis. It yields readability to four decimal places to the right of the decimal point (up to .0001 g). It is extremely sensitive and requires a draft-free location on aRead MoreEvaluating Kuhn ´s Theory of Scientific Development Essay1545 Words   |  7 Pagesas Antoine-Laurent Lavoisier’s paradigm is incommensurable with that of Joseph Priestley’s in chemistry (Oberheim Hoyningen-Huene, 2012). Paul Feyerabend used incommensurable to describe the lack of logical relations between the concepts of fundamental theories in his critique of logical empiricist’s models of explanation and reduction. Stating that in the event of scientific revolution, when fundamental change occurs there is a change in perspective which is the birth of a new conception of theRead MoreQuantitative Me thods for Business Paper1652 Words   |  7 PagesKent Jackson 11AM-12:20PM GB 202 Quantitative techniques are mathematical and reproducible. Regression analysis is an example of one such technique. Statistical analysis is also an example of a quantitative technique. Quantitative techniques are applied for business analysis to optimize decision making IE profit maximization and cost minimization.

The vacuum and atmosphere are switched to the measurement atmosphere by the operation of one button. When X-rays (primary X-rays) are illuminated from the X-ray tube to the specimen, fluorescence X-rays having wavelengths (energies) peculiar to the constituent elements of the specimen are generated from the elements. Qualitative analysis can be made by investigating the wavelengths of the fluorescence X-rays and quantitative analysis by investigating the X-ray dose. The energies areRead MorePhysics Of The Jsx 3222 Analyzer1156 Words   |  5 Pagesswitched to the measurement atmosphere by the one button operation. When X-rays (primary X-rays) are illuminated from the X-ray tube to the specimen, fluorescence X-rays having wavelengths (energies) peculiar to the constituent elements of the specimen are produced from the elements. There are two methods to investigate the energies. The first method is Qualitative analysis which can be made by investigating the wavelengths of the fluorescence X-rays and the other method is quantitative analysis by
