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

“Is Starch Permeable in Cells? Abstract This report presents the weights of 3 samples of water with various amounts of solute after the use of osmosis. Three different tests were performed‚ each with a beaker of water containing varying amounts of starch from 30% concentration (12.5 grams of water) to 15% concentration (9.5 grams of water)‚ and then 0% (10.5 grams of water). To start this experiment‚ we put water into a make-shift dialysis tube‚ a type of semi-permeable membrane tubing made

Krupa Desai Cell Biology April 3‚ 2013 Lab: Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato‚ which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test

department Data security – Lab # 1 Lab Description Set-UID is an important security mechanism in Unix operating systems. When a Set-UID program is run‚ it assumes the owner’s privileges. For example‚ if the program’s owner is root‚ then when anyone runs this program‚ the program gains the root’s privileges during its execution. Set-UID allows us to do many interesting things‚ but unfortunately‚ it is also the culprit of many bad things. Therefore‚ the objective of this lab is two-fold: • Appreciate
