Abstract

In a modern version of Young's double slit experiment, a laser beam passes through two narrow slits and creates an interference pattern of bright and dark fringes on a distant screen. We place magnifying glasses between the double-slit and the screen, and when a laser beam passes through the double-slit and magnifying glasses, strange patterns will appear on the screen.
