In the Young's double slit experiment, the intensities at two points `P_(1)` and `P_(2)` on the screen are respectively `I_(1)` and `I_(2)` If `P_(1)` is located at the centre of a bright fringe and `P_(2)` is located at a distance equal to a quarter of fringe width from `P_(1)` then `I_(1)/I_(2)` is
