Red Light with wave length 600nm coming from a He-Ne laser, passes through a 0.3mm wide slit. The reflection image is observed on a plate placed at a distance of 4m. Defining as a range of a bright fringe the distance between the dark sides on both sides, calculate: (a)The range of the central bright fringe. (b)The range of the first bright fringe, immediately after the central bright fringe, to one side or the other. (c)The range of the central bright fringe if the entire layout (slit, plate and the space between them) is submerged in water (n = 1,33)
