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

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

Abstract: This experiment explores the technique of absorption spectroscopy. The procedures deal with the wavelengths and absorption of dyes in a sample of grape Kool-aid. The use of Beer’s Law helps to determine values of absorption. Introduction: This experiment demonstrates another technique used in the analysis molecules with light. The study of light absorbed my molecules is known as absorption spectroscopy. This is very easily the opposite of emission spectroscopy because it occurs when
