Part AOne day, after pulling down your window shade, you notice thatsunlight is passing through a pinhole in the shade and making a smallpatch of light on the far wall. Having recently studied optics in yourphysics class, you're not too surprised to see that the patch of lightseems to be a circular diffraction pattern.
