![]() Anyone performing any part of these demonstrations, even with revisions, knowingly and voluntarily assumes all risks associated with them. We built our setup to prove the theory behind measuring the diameter of the hair by using a laser beam. These risks include, without limitation, bodily injury (and possibly death), including risks to health that may be temporary or permanent and that may exacerbate a pre-existing medical condition and property loss or damage. Experiment Results: 5.Find the thickness of hair by using the second equation which is:a L/Xm. Performing all or any portion of any of these demonstrations, with or without revisions not depicted here entails inherent risks. The demonstrations included here are within the public domain and can be found in materials contained in libraries, bookstores, and through electronic sources. We will work here with light waves, however those concepts are equally applicable to different types of waves (for example, sound waves). The University of Iowa is not responsible for demonstrations performed by those using their own equipment or who choose to use this reference material for their own purpose. Fraunhofer Diffraction Fraunhofer Diffraction Goals: In this virtual lab you will learn concepts related to the phenomena of diffraction of waves. Kerzerashvili, "Abstract: Advanced Optics with Laser Pointer and Metersticks", 2005 Apparatus Competition, Salt Lake City, UT.ĭisclaimer: These demonstrations are provided only for illustrative use by persons affiliated with The University of Iowa and only under the direction of a trained instructor or physicist. The two laser sources both provided consistent estimates of the hair diameter of approximately 50 m. Chiaverina, "5.6, Diffraction", Light Science, Physics and Visual Arts, p. The width of a human hair sourced from a female elementary school student was measured by light diffraction using red and blue laser pointers.
