Question: A thin, flat object in which a square hole 30.0 mm on a side has been cut is illuminated with a point source. Light that passes through the hole strikes a screen 300 mm behind the object. Call the direction normal to the screen the z direction. The point source is shifted away from the center of the hole by 150 mm in the positive x direction. The point source is centered on the hole in the y direction and is 300 mm in front of the object in the z direction. What is the length of the bright region on the screen along the x axis?
