Introduction: single slit diffraction
More Details: You have been asked to measure the width of a slit in a piece of paper. You mount the paper 80 centimeters from a screen and illuminate it from behind with laser light
of wavelength 633 nanometers (in air). You mark two of the intensity minima and measure the distance between them to be 17.9 millimeters. What is the width of the
