Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

PepsiCo Inc. was created in 1965 as a result of the merger of Pepsi Cola‚ created in 1898 and Frito Lay‚ created in 1932. Both companies agreed that by merging they would gain access to a wider market. Diversification was part of the company’s strategy from the beginning‚ and we can say that because Frito-Lay was the result of a merger between two different producers of salty snacks. PepsiCo Inc. was clear as to what type of diversification strategy to use‚ and when to diversify. Their first strategy

Population Ecology Ingrid Rhody BIO/101 March 7‚ 213 Kirsten Hagen MS Population Ecology Population ecology is the affect of a populations density and extension. When a group of single species occupy the same general area it is known as a population. This group of species will rely on resources and the same environmental atmosphere. The number of species within a group that occupy the same area or habitat is known as population density. Some ecologists use different types of techniques

Women´s in the 19th Century European and American women in the nineteenth century lived in an age characterized by gender inequality. At the beginning of the century‚ women enjoyed few of the legal‚ social‚ or political rights that are now taken for granted in western countries: they could not vote‚ could not sue or be sued‚ could not testify in court‚ had extremely limited control over personal property after marriage‚ were rarely granted legal custody of their children in cases of divorce‚ and

Unit 19: Developing Teams in Business Assignment 3 P4 In this assignment I will be discussing our snack group‚ how well we worked as a team and how team working is very important. Teamwork is defined in Webster’s New World Dictionary as "a joint action by a group of people‚ in which each person subordinates his or her individual interests and opinions to the unity and efficiency of the group." This does not mean that the individual is not important anymore‚ but‚ it does mean that effective and

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Michael Ames Ms. Martin IPS Per. 1 11-3-09 Sludge Lab Report A few weeks ago‚ I got a container full of “sludge”. I was asked to separate it into its four components and identify each one to help me better understand how to separate mixtures ad identify substances. My original sludge had a liquid on top and solid(s) on the bottom. The liquid was clear‚ and most of the solid was tan. There was a small layer of blackish/brownish particles in the middle of the tan solid. There were small yellow
