Understanding Light Interference and Diffraction: Insights from Physics

This summer 2014 study by Gernot Laicher at the University of Utah's Physics & Astronomy Department delves into the fascinating phenomena of light interference and diffraction. It explores concepts such as single and double slit experiments, the width of slits, and the impact of these parameters on light patterns observed on a screen. The research highlights calculations involving the radius of dark rings in single slit experiments and path length differences in double slit configurations, providing a foundational understanding of wave interactions in optical physics.

  2. Screen Single Slit Width=a ymin 2ymin L

  3. ymin= RADIUS of first dark ring q = diameter of hole d = distance from hole to screen

  4. Screen Double Slit Width = a Separation = d ymax 4ymax L

  5. …if you had multiple colors Screen Double Slit Width = a Separation = d ymax 4ymax L

  6. difference in path length Qn d Diffraction grating
