5) You are looking at the fringe pattern on a screen produced by a laser beam passing through a pair of closely-placed slits, and then travelling about a meter until the pattern hits the screen. A) You put a thin sheet of glass over one of the slits (one slit only). The effect of the glass is to add exactly half of a wavelength to the light that passes through that one slit. Explain precisely
