two closely spaced slits are cut into a piece of cardboard. A green light is used to illuminate the slits. a) what would be observed on a screen placed L, meters behind the cardboard? does the observation you described in a) support the wave theory or the particle theory of light? justify your answer. b) the green light is then replaced with a red light. use the equation delta x=lambdaL/d to explain how the image on the screen would differ.
I don;t understand what question is asking . for a i think i would observe a bright light on the screen. for part b...why would the observation change if the color of light is changed?
