Multiple ChoiceLight from a 600 nm laser is shown through a single slit of unknown width. If a screen is placed 4.5 m behind the slit captures a diffraction patter with a central bright fringe of width 20 mm, what is the width of the single slit?25111Has a video solution.
Multiple ChoiceA single slit is illuminated by coherent monochromatic light at 680nm. On a screen 2.9m behind the slit, a central bright spot is observed to have a width of 39mm. What is the width of the single slit?113
Multiple ChoiceA carbon dioxide laser produces 10.6 μm electromagnetic waves, which pass through a circular aperture with diameter 1.0 mm. What is the approximate width of the laser beam when it strikes a target 3.0 m away?75
