Diffraction of Light Shannon Berg December 2, 2010 Physics 255b Section 4 Object The main purpose of this lab is to investigate the wave nature of light through diffraction patterns, learning how to use the light sensor to measure different light intensities, learning how to use the rotary motion sensor to measure relative positions, and finally to record the data and plot intensity versus position. Through this experiment we will be able to observe the interference pattern formed by monochromatic light passing through a double and single slit, find the maximum and minimum intensities by analyzing both interference patterns, and make assumptions about light based on our measurements. Apparatus 1) PASPORT Light Sensor 2) 2 USB Links 3) PASPORT Rotary Motion Sensor 4) Basic Optics System 5) Aperture Bracket 6) Linear Translator 7) Slit Accessories 8) Diode Laser Procedure 1) Place the diode laser on the end of the optics bench and connect the laser to the power supply.
