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

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

Film #2 In the series documentary‚ “7 Up‚ 14 Up‚ and 21 Up” we take a look at a handful of individuals who’s lives are chronicled to depict if their socioeconomic background in the United States determines their future. Every seven years‚ the director follows up with these individuals to attain some insight about what stage they are in their lives; how they are doing‚ if they have the same goals as said when they were seven years old‚ and to track their development throughout the years into adulthood

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

Brand Analysis What is a brand? A brand is often mistaken as a variety of different things and it’s important to understand its ambiguous nature. A brand is not simply the logo‚ nor the visual identity. A brand is not the product‚ the slogan or the advertising campaign. A brand is not even controlled by the company behind it. Rather a brand is a collection of perceptions that reside in the mind of the customer. It is the gut feeling a customer has about you. While you may not have direct control

For this lab it was necessary to bring a watch with a second hand‚ as well as personal protective gear: lab coat‚ safety goggles‚ and safety gloves. It was best to work in pairs and one partner needed to be a timekeeper while the other one would record the data. The timekeeper then would announce every 5 second interval‚ beginning from when the enzyme was added to the tube. On the other hand‚ the recorder would read and record the absorbance from the spectrometer at the 5 second intervals. This was

Drugs For this assignment we had to choose a few drugs and write a paper about them. There are many drugs in the world to choose from. I chose cocaine and methamphetamine to writeabout. Cocaine and methamphetamine are similar to other legal drugs in the U.S. Cocaine is one of the oldest known psychoactive substances—it dates back as far as the Incan Empire where it was used as a local anesthetic. Cocaine is derived from the leaves of the coca plant. Modern day cocaine was invented by a man named
