Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Abstract The objective of this lab was to determine the convective heat transfer coefficient of a heated sphere in an quiescent environment. In the experiment a hot brass sphere was put into water and cooled. The temperature of the sphere was recorded over a time of 600 seconds to see how it cooled and given temperature was recorded every 20 seconds. Results were then calculated at both of the time values 300 and 600 seconds. For the experimental results at time 300 seconds‚ the Rayleigh number

Helicopter Lab * Objectives: the objective is to study the effect of variables on the helicopters’ flight. The goal is to observe which can stay in the air for the most time. * List of materials: 3 patterns for a paper helicopter‚ scissors‚ tape ruler‚ and paper clip. * Procedures: 1. Cut the solid lines and fold the dashed ones. Fold A toward you and B from you to form wings. Then fold C and D inward to overlap‚ forming the body. Fold up the bottom on the dashed line and hold it

Taylor Durham Nutrition 101 Mr. Oropallo Lab Report #2: Fat Extraction From Food What is a triglyceride? Draw its structure. A molecule that contains three fatty acids attached at the oxygen atoms of glycerol. What are the differences between saturated and unsaturated fats? Drawn an example of each. If all bonds are single‚ the fatty acid molecule is saturated. If there is a double bond among the carbon atoms‚ the fatty acid molecule is unsaturated. What form does each of these fats take at

Sample Short Lab Report By Charles M Borener Jr April 24‚ 2009 Kinetic Friction Experiment #13 Joe Solution E00123456 Partner - Jane Answers PHY 221 Lab Instructor – Chuck Borener Thursday‚ 11 AM – 1 PM Lecture Instructor – Dr. Jacobs Abstract In this experiment‚ we test factors which effect friction. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface effects friction. We found that the surface area of the block did not change

Littlefield Labs 1 Capacity Management at Littlefield Labs I. Introduction There are 3 stations in the game called sample preparing‚ testing‚ and centrifuging‚ while there are 4 steps to process the jobs. Before the game started‚ we tried to familiarize with the process of the laboratories and calculating the costs (both fixed and variable costs) based on the information on the sheet given. We did not intend to buy any machines too early‚ as we wanted to see the demand fluctuation and the
