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

Vitamin C Molecule Investigation Thomas Philpott Introduction Vitamin C (ascorbic acid) is an essential component of human nutrition‚ as it is an antioxidant that the body requires. Having a deficiency in Vitamin C can lead to scurvy‚ a disease characterized by abnormalities in human bones and teeth. Fruits and vegetables are common sources of Vitamin C‚ notably oranges and citrus fruits. Cooking and the application of heat destroy the vitamin so such fruits must be raw in order to obtain the

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

Beetroot Practical 2.8 An investigation to find out whether the raise of temperature will increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim

Stretches of a river can be different in terms of their processes and landforms. Introduction: My investigation is a study of hydrology‚ as I want to find out how and why a rivers channel‚ flow and valley characteristics change as you move downstream from its upper course to its mouth. These changes are represented in the Bradshaw Model (fig 1)‚ a fluvial model that describes changes in the river channel and flow characteristics between different courses along the river. Based on three factors

Samuel Turner Mr. Eichbauer IB Chemistry II – Period 6 16 February 2015 Investigation of the Effects of Acid Rain Background Information Acid rain is when there is a mix of wet and dry deposited material in the atmosphere that have higher levels of nitric and sulfuring acid. These chemicals formed can be from natural causes‚ like volcanoes and the decay of vegetation‚ or man made causes like fossil fuel combustion. Acid rain can be measured using the pH scale‚ and will always be on the lower
