PhysLab_S10_Sky_   Diffraction Pinyin name: Tian Yunfan English name: Sky Date: 20/5/2010 Temperature: 25 °C  Humidity: 72% PROBLEM DESCRIPTION This   Lab   investigates   relative   light   intensity  distribution of  single   slit   diffraction  and the linearity  between light intensity and photonic current. In lab, the two problems were approached using  three   basic   scientific   methods.   First,   predictions  were made about the light intensity distribution and  the   relationship   between   light   intensity   and  photronic   current.   Second,   date   and   graph   were  tested   and   recorded.   Finally,   the   results   were  analyzed and conclusions were made. The lab required use of an optical bench, He-Ne  laser, single slit, photo-cell, light spot galvanometer,  and steel ruler. PREDICTION

“A long slit of infinitesimal width which is illuminated  by light diffracts the light into a series of circular  waves and the wave front which emerges from the  slit is a cylindrical wave of uniform intensity”—wiki
