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

Experiment 3 : Identification of food constituents in milk Objectives To compare the composition of two different kinds of milk for fats‚ protein and reducing sugar. Introduction In this experiment two milk samples are given and its compositions are tested using different methods such as using benedict solution to test the presence of reducing sugar‚ using copper II sulphate to test the presence of protein‚ using K3( to test the presence of fat. However in this experiment‚ not only are

3.2 “Lab-on-a-Chip” A Lab-on-a-Chip (LOC) device‚ also known as a micro-total-analytical system (microTAS) or microfluidics device‚ is a device that can integrate miniaturized laboratory functions (such as separation and analysis of components of a mixture) on a single microprocessor chip using extremely small fluid volumes on the order of nanoliters to picoliters. From a technology categorization perspective‚ LOCs can be viewed as a subset of microelectromechanical systems (MEMS) and combine

it’s unlikely to hear it described as being an easy task. Nadia Bozak’s short story "Heavy Metal Housekeeping" encourages the idea that good parenting is defined by the ability to sacrifice one’s own freedom and desires with the intention of providing the child with better opportunities in life. This belief is reinforced by the symbolism of dirty and clean clothes‚ the self-defense mechanism behind heavy metal appearances‚ and the mother forfeiting her life’s goals for her son. A quick glance at Bozak’s

Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface
