BACKGROUND INFORMATION: Youngs experiment involved sunlight being allowed to pass through a pinhole, S and then at a considerable distance away , through pinholes S1 and S2. The two sets of spherical waves emerging from the two holes interfered with each otherinsuch a way as to form a symmetrical pattern of varying intensity on the screen AC. This experiment is shown below The mathematical formula that was derived from this experiment is ? = (a * y)/D, which can be re- arranged so that the seperation of the two slits is the subject of the equation, a = (? * D)/y EQUIPMENT: * Monochromatic light (red laser) * Measuring tape * Double slit * Piece of paper * Pen PROCEDURE: 1. Set up the apparutus as per the diagram below: 2. Turn on the Monochromatic light and put the double slit in place so that an image similar to the one below is visible on the paper 3. Mark...
